Fixed DefaultMockitoSession constructor.

It was not removing the UniversalTestListener when initmocks()
failed, which would cause subsequent tests to fail because they could
not start a new session.

To test it, run the following command in a pristine device running
Android TM (without an updated adservices apk) - a lot of tests will
fail due to missing classes and methods.

$ atest AdServicesServiceCoreUnitTests 2>&1 | tee ~/tmp/log.txt && grep "Unfinished mocking session" ~/tmp/log.txt | wc

Without this patch, it would return ~216 occurrences; with it, it's 0.

Test: manual verification (see above)
