remove ringtone logic (only make it depend on notification!)

this commit removes the logic to play the ringtone in CallNotificationActivity. Playing ringtone should only be controlled by the notification channel from OS!

furthermore the checks if a call is stopped or is still ongoing etc was removed from CallNotificationActivity. Instead the CallNotificationActivity now is completely dependent on the notification. If the notification is canceled, the Activity stops. If the Notification is ongoing and hangup of accept call is clicked, then the notification is canceled (including the ringtone).
