Fixed boot receiver problems. Added expection handling including unhandled exceptions ... Students should still add  notificaitons to let the user know that the app launched after launch. Also, I noticed that step counter broke after one of the restarts - so I am quite sure the error is somewhere to be found in the activation of the service.

Again again
