Pitest seems to ignore or never trigger Mockito's UnnecessaryStubbingException

[daniel-frak]

Given a mutation, if a test mutated this way would normally fail with org.mockito.exceptions.misusing.UnnecessaryStubbingException, Pitest will report it as having survived.

It seems that Pitest never triggers Mockito's UnnecessaryStubbing checks.

I have encountered this issue more than once, where I was doing the same modifications as Pitest but getting different results, before realising that Pitest behaves as if all stubbings were lenient().
