Split handleGetIdentity in two functions:
- The one which takes only a SFS is suitable for being used in handling the "GetIdentity" FCP message
- The one which takes two identity objects will be used by event-notification deployment
- The new "Type" fields is necessary because event-notifications will have their own "Message" value.
JavaDoc and remove obsolete throws declaration
Fix handleGetIdentity:
- Return the actual SFS
- Don't add "Message" in the function which will be used for event-notifications, we won't need it there
