When creating a job from another, i'd like to keep the ownership information in this way :

. If I'm the owner of the base job, i'd like to keep my co-owners on my new job.
. If I'm a co-owner, i become the owner of the new job, the owner of the base job becomes a co-owner on the new one, and i keep the other co-owners on my new job.

In this way, i don't need to set up ownership each time I create a job by duplication.
