Bug 28069: (bug 27715 follow-up) Fix sort for lists

Sort functionality has been broken by bug 27715. We need to specify the
table.column in the datatable init

Note that "count" needs to be handled separately (which is a bit dirty
but cannot find something better)

Test plan:
Create some lists, add contents, change owner and dates
Sort using the different attributes and confirm that it's now working
