Stabilize the app when permissions have been revoked. Moved the start…

… service to only after the permission check is complete.

In the stop service, only stop the service if notifications are enabled, due to a weird scenario where the service might start and immediately end due to lack of notifications, resulting in an app crash.
How did we end up like this.
