`IllegalStateException` if tested class is in `org.utbot` package

[alisevych]

Description

IllegalStateException: Class contains not only one method with the required signature is thrown from UtBotSymbolicEngine
on ExceptionClusteringExamples copy-pasted to a separate project.

To Reproduce

1. Install UnitTestBot plugin built from main in IntelliJ IDEA
2. Create IntelliJ project with JDK 1.8
3. Open utbot project, copy exceptions package from utbot-samples
4. Create org.utbot package in IntelliJ project and paste exceptions into it
5. Generate tests for ExceptionClusteringExamples with default settings (any Mocking strategy can be selected)

Expected behavior

No exception is expected to be thrown in IDE.
Tests are expected to be successfully generated - just like in utbot.

Actual behavior

IllegalStateException: Class contains not only one method with the required signature is thrown from UtBotSymbolicEngine

The issue is reproducing on Release 2023.3 plugin

[sofurihafe]

@alisevych, we prohibit naming packages as org.utbot.*, in our case it's org.utbot.exceptions which was just filtered out from Soot Scene, that's the cause of the fail.

In order to be able to run samples, name package as org.utbot.examples.*.
