Reviewed by Jean-Yves Avenard.

We were previously using default mode when capturing microphone while trying to output audio to receiver.
Instead, we now use voice chat mode in that case, this allows smooth audio transition.

In addition, we reset whether to use receiver if the audio output id is set back to the empty string.

We do not expose voice chat as a specific AudioSession mode.
Instead we consider it is a special case of AudioSession::Mode::VideoChat.

Manually tested.
