Create notification early for headset events

Browse Source 
Headset events are the only place where we are forced to use the startForegroundService call which requires us to call startForeground() within 5 sec.

This will *usually* work fine, but fails if the device somehow failes to be fast enough OR if there is no song available.
Having an option to create a notification in onStart() in any case avoids the ANR crash in such strange cases.
