Reset the audio stream volume to fix low in-call volume bug

Due to a bug in the OMX system, the audio stream volume
is set to 0 after it was set to it's default volume.

Calling PhoneUtils.resetAudioStreamVolume()
triggers the system to reset the volume.

This should be called on every place where
is switched between audio modes.

REMARK: I think it only appears on the voice call stream,
        but to be sure I also do it on the bluetooth stream.
