unnecessary stubbings errors are swallowed when tests run with Mockito

[henrypoon]

The following two issues are found when I have unnecessary stubbing in test with Mockito.

1. unnecessary stubbings errors are swallowed and test passed when test_filter is being used, however, it failed as expected without test_filter
2. unnecessary stubbings errors are NOT reported in JUnit reports regardless of using test_filter or not. The JUnit report shows all tests have passed.

Please follow this repo to reproduce the issue locally.

ISTM there isn't anything Bazel related going on here. This is seems more related to mockito/mockito#1924. From a superficial reading of that and all the linked issues, it appears mockito strict stubbing behavior can often be surprising.
