Cancel NotificationTimeout alarms when canceling notification

If alarms with long timeouts are created, there is a risk of a
crash in system_server because of alarm creation limit is reached:

java.lang.IllegalStateException: Maximum limit of concurrent alarms 500
reached for uid: 1000, callingPackage: android

To avoid this cancel alarms if Notifications are canceled.
