Disabled ducking test for auto

The expected behaviour for audio focus is different for auto. Particular
the ducking behaviour. This was done in order to give oem more control of
what audio gets played and when. Three test cases were disabled for auto:
testAudioFocusRequestForceDuckNotA11y
testAudioFocusRequestGainLossTransientDuckHandler
testAudioFocusRequestGainLossTransientDuck
