jubb 8439d57115 refactor: let the periodic work run more frequently and never fail from excessive retries preventing from re-running.
remove resume pending jobs from ApplicationContext onCreate and handle in home activity's onCreate instead.

prevent some illegal argument exceptions from Random.kt by returning null if empty
