[BETA] Bluetooth media controls (play/pause) not working reliably

Progress, and it may be the same root cause as another report today. The old app declared a media button receiver and the rewrite dropped it, which means a press only lands if we are the session Android currently considers in charge. When a Bluetooth route drops that is briefly not us, and the press has nowhere to go, which fits your dropped presses and the Sony needing a throwaway first one.
