VoiceInteraction tests: Handle null args in onshow().
Due to a concurrency bug in VoiceInteractionManagerService, the args may
be null even when the test code sends a non-null value in the request.
This was causing the service to sometimes crash, which was causing the
tests to fail with timeout errors.
The arg can also normally be null if an app doesn't provide a Bundle
when calling Activity.startLocalVoiceInteraction() or
Activity.showAssist(), so it's good to handle this in the test service
anyway.
