Remove static injections in ListenerService

- Get other classes via Inject annotation
- Remove no longer needed Utils methods (relates to #736)
- Create tests for ListenerService and AuthMeBlockListener
- Performance improvement: keep unrestricted names as Set instead of List for faster contains() method
