PlayerHater is not loaded yet or has been shut down

[flavioarfaria]

Steps to reproduce:

1. Set the PlayerHater to start in onResume() and to release in onPause();
2. In a button click event, call play() on a Song being streamed from the web (I haven't tested with any other data source);
3. Press back button just after the notification ticker slides in.

It doesn't happen every time, but i's fairly easy to reproduce. Digging through the source code I could notice that this happens because the plugin tries to start the player service:

getBinder().startForeground(NOTIFICATION_NU, getNotification());

In the code above, getBinder() tries to access a reference to the PlayerHater instance, which has been destroyed, since the Activity has run onPause() when back was pressed.

Interesting - I think I know how to address this and will give it a shot.
