fix(Android/ConnectionService): mic not working

Turns out the microphone will not work on some devices when starting in
"audio only", because the audio mode is not set to the MODE_IN_COMMUNICATION,
but to the MODE_IN_CALL. Calling setAudioModeIsVoip(true) makes
the system adjust to MODE_IN_COMMUNICATION and the mic works fine.
