Fixes #3700, so external projects implementing MockCreationListener does no longer get a raw types warning they do not have control over, by using generic type T.
I did see more classes using raw type when using MockCreationSettings class, but this will at least remove the warning from projects using the MockCreationListener.

When using the MockCreationListener implementation should now use generic type, instead of raw type:

public class NoOpTestListener<T> implements MockitoTestListener<T> {

    @Override
    public void testFinished(TestFinishedEvent event) {}

    @Override
    public void onMockCreated(Object mock, MockCreationSettings<T> settings) {}
}

Instead of

public class NoOpTestListener implements MockitoTestListener {

    @Override
    public void testFinished(TestFinishedEvent event) {}

    @Override
    public void onMockCreated(Object mock, MockCreationSettings settings) {}
}
