Several improvements in the event admin handler:
- add checking when the factory is initializing instead of during the instance creation
- subscribers are no more ignored when an error occurs
- improve error messages
- fix a mistake (eventadmins instead of eventadmin) in the artifactid
- the handler now requires the event admin as an iPOJO dependency, this avoids tracking the service
