Allow jobs to be filtered by contact list

Rather than showing all jobs that have been ‘copied’ from a contact list
I think it makes more sense to group them under the contact list. This
way it’s easier to see what messages have been sent to a given group of
contacts over time.

Part of this work means the API needs to return only jobs that have been
created from a given contact list, when asked.
