convert PlayerHolder to Singleton, handle context within, bugfix ServiceConnection leak

Browse source 
- bugfix: have ServiceConnection created only once!

- select the context within the PlayerHolder to start, stop, bind or unbind the service
  -> we have to make sure the Service is started AND stopped within the same context
  -> so let PlayerHolder be the one to select the context

- remove removeListener() and replace the call with setListener(null)
- Compatibility: use ContextCompat.startForegroundService instead of startService()
