Fixing token repetition bug

Fixing token repetition bug

BUG=451598
When we stop playing, we need to clear the token stored in the AudioManager. Otherwise the old token will start playing while the new one is being encoded, which confuses the decoder on the receiving device.

See the linked bug for details. When we stop playing, we need to clear the token
stored in the AudioManager. Otherwise it will start playing while the next token
is being encoded, which confuses the decoder on the receiving device.

should_be_playing_[type] ? playing_token_[type] : "";
We no longer need this check since we're not storing stale tokens anymore.

This builder is broken. Landing under a different CL with my @chromium account:
