Fix the regression bug: assume failure is not marked as skipped

fix #945

Finally I got that, first-line statement assumeTrue(false) is just something like @Ignore(if false == true)...

Though I have a question, not much related to this PR, what if this statement is not in the first line of the method body? Should it be "skipped"? But that's a little bit wired to me (beginner of junit), because some code did run, but it's skipped.

It's ok whether the assume statement is in the first line or not, the Test Runner will handle that situation and return back the right output to the output parser.

The Assume is used to do some condition check, so you can put wherever you want as long as you want to do some condition check. For example, if I want to make sure the test code will only be executed in the Windows environment, then I can write: AssumeTrue(System.getProperty("os.name").startsWith("Windows"))
