Fixed restoreOnStartup for all QueryablePersistenceServices

the problem was, that every QueryablePersistenceService which is a ManagedService too, has not been initialized if the PersistenceManager wants to restore the saved state at startup, because the ManagedService.update method is called later.

Sense isn't query able so it doesn't need the StateRestorer, right?
