VoiceSearchTestCase.testVoiceSearchLocalePrefSynchronization requires entering/exiting the voice search UI to work.  However, GoogleS3Kit is designed in such a way that it's difficult to do this without actually accessing the device microphone.  As such, the microphone permissions dialog gets displayed and prevents the rest of the tests from being run.  We should update this test to run without actually requesting microphone access so that these can get run on devices.
