Reviewed by Eric Carlson.

Replace the boolean to update the sample buffer by a minimum buffer sample frames, which is set when render fails.
This minimum buffer sample frames is used to compute a minimum buffer size when setting up the audio unit.

Update Mock implementation to cover that case.
We do this by triggering this code path when triggerMockMicrophoneConfigurationChange is called.
We also update the capture verification timer so that timer for mock unit is reduced to 1 second.

Update LayoutTests/fast/mediastream/mediastreamtrack-configurationchange.html to cover that case.
