Show jobs on contact list

It’s a bit unintuitive that starting a job from a contact list makes a
copy of the file, which has no relationship to the list it was copied
from. This is more of an implementation detail, rather than something
that comes from people’s mental models of what is going on. Or at least
that’s what I hypothesise.

I think it’s clearer to show jobs that come from contact lists within
the lists that they were created from. By naming the jobs by template
this gives a clearer view of what messages have been sent to the group
over time.
