Remove hardcoded audio route in video provider.

The video provider always calls exitVideo() and as a result always sets
the audio mode to EARPIECE when any call starts, negating any automatic
setting done by telecomm (like bluetooth).

This change has three items:
1. Only set the audio mode if we are exiting a previously entered video
call.
2. When setting audio on exit, set it to the mode that was previously
saved when the video call was entered.
3. Convert usages of the private AudioMode to the public CallStateAudio.
