### Submitter checklist
- [x] Make sure you are opening from a **topic/feature/bugfix branch** (right side) and not your main branch!
- [x] Ensure that the pull request title represents the desired changelog entry
- [x] Please describe what you did
- [ ] Link to relevant issues in GitHub or Jira
- [ ] Link to relevant pull requests, esp. upstream and downstream changes
- [ ] Ensure you have provided tests - that demonstrates feature works or fixes the issue

In our analysis of the project, we observed that

1. 3 unnecessary stubbings which stubbed getChangeSet method, getChangeSets method, and getNumber method in ChangesSinceLastSuccessfulBuildMacroTest.createBuild are created but are only executed by some of the method calls in the test ChangesSinceLastSuccessfulBuildMacroTest.testGetContent_shouldGetPreviousBuildsThatArentSuccessful_HUDSON3519. We duplicated the createBuild method, removed the unnecessary stubbings, named it createBuild2, and applied the new method to the method call which does not execute the stubbings in the test.

2. 2 unnecessary stubbings which stubbed getResult method, getChangeSet method in ChangesSinceLastSuccessfulBuildMacroTest.createBuildWithAffectedFiles are are only executed by some of the method calls in 8 tests: ChangesSinceLastSuccessfulBuildMacroTest.testGetContent_shouldGetPreviousBuildFailures, ChangesSinceLastSuccessfulBuildMacroTest.testGetContent_whenReverseOrderIsTrueShouldReverseOrderOfChanges, ChangesSinceLastSuccessfulBuildMacroTest.testGetContent_shouldGetPreviousBuildsThatArentSuccessful_HUDSON3519, ChangesSinceLastSuccessfulBuildMacroTest.testShouldPrintDate,
   ChangesSinceLastSuccessfulBuildMacroTest.testShouldPrintRevision, ChangesSinceLastSuccessfulBuildMacroTest.testShouldPrintPath,
   ChangesSinceLastSuccessfulBuildMacroTest.testWhenShowPathsIsTrueShouldPrintPath, ChangesSinceLastSuccessfulBuildMacroTest.testRegexReplace;
   We duplicated the createBuild method, removed the unnecessary stubbings, named it createBuild3, and applied the new method to the method call which does not execute the stubbings in the test.

3. 1 unnecessary stubbing which stubbed getResult method in ChangesSinceLastSuccessfulBuildMacroTest.createBuildWithNoChangeSets is created but is never executed. We removed it.

4. 2 unnecessary stubbings which stubbed getResult method, getChangeSet method in ChangesSinceLastSuccessfulBuildMacroTest.createBuildWithNoChanges are created but are never executed. WE removed them

5. 1 unnecessary stubbing which stubbed iterator method in ChangesSinceLastSuccessfulBuildMacroTest.createChangeLog is created but is only executed by some of the method calls in the test ChangesSinceLastSuccessfulBuildMacroTest.testGetContent_shouldGetPreviousBuildsThatArentSuccessful_HUDSON3519.We duplicated the method, removed the unnecessary stubbings from the new duplicated method, named it createChangeLog2, and applied to the specific method call that doesn't execute the stubbing.

6. 1 unnecessary stubbing which stubbed iterator method in ChangesSinceLastSuccessfulBuildMacroTest.createBuildWithAffectedFiles.createEmptyChangeLog is created but is never executed. We removed it.

7. 1 unnecessary stubbing in the test 'ChangesSinceLastSuccessfulBuildMacroTest.testGetContent_shouldGetPreviousBuildsThatArentSuccessful_HUDSON3519' is created but never executed. We removed it.

8. 1 unnecessary stubbing in the test 'ChangesSinceLastSuccessfulBuildMacroTest. testGetContent_whenReverseOrderIsTrueShouldReverseOrderOfChanges' is created but never executed. We removed it.

Unnecessary stubbings are stubbed method calls that were never realized during test execution. Mockito recommends to remove unnecessary stubbings (https://www.javadoc.io/doc/org.mockito/mockito-core/latest/org/mockito/exceptions/misusing/UnnecessaryStubbingException.html).

We propose below a solution to remove the unnecessary stubbings.
