Let response.status == 404 flow through the restangular interceptor to
allow more fine grain user message to be defined in given UI context.
Handle case where not ELFIN ACTEUR is defined. Provide clearer user
feedback in such case as well as warn log.
Added test not to perform DEREGISTRATION for case oldId => newId :

Trigger validation for create mode as well.

Remove hb-choose-actor-elfin obsolete attribute.
Remove hb-choose-actor-elfin obsolete attribute.
Removed logic now included into hb-choose-actor for owner selection.
