Don't over-specify testcases with verifyNoMoreInteractions.

In this specific case, there is a race condition between
verify(...).onProgramInfoChanged(...) and verifyNoMoreInteractions call.
As it's being called in the middle of the testcases, it's not possible to
pull the callback from the radio service to prevent the race condition.
However, Mockito docs ask to not overuse this method for over-specification
of the tests, so let's just comply with what the doc says.
