Change-Id: I8be43e899a14d184374b422a381b0db839709fbf
settings: Move headset option, hide MoreDeviceSettings if empty

 * This option fits much better in the sound menu under "automation
   and effects", and on many devices it's the only option in the
   "More..." menu under Tap & Pay.
 * Move it, and remove the MoreDeviceSettings top-level category if
   there's nothing else in it.
