Fix TTS to play all unread messages when background audio is playing.

Previously, helper would abandon audio focus after the first message
had been played. This plays all the messages when there is no background
audio competing for the audio focus, but doesn't work when there is.
Instead, we should abandon audio focus after all messages have been played.
