Mats Kindahl 9a64385f34 Use regrole for job owner
Instead of using a user name to register the owner of a job, we use
regrole. This allows renames to work properly since the underlying OID
does not change when the owner name changes.

We add a check when calling `DROP ROLE` that there is no job with that
owner and generate an error if there is.
