Bug 29149: Add the capability to provide more info to the background job detail view

(Patch extracted from bug 28445 to make it reusable for bug 23678)
We already had the need for that, when bibliographic records are
modified in batch we wanted to add a "Add to list" feature, and so pass
a list of lists/virtual shelves to the template.

Here (in 28445) we will want to pass the infos of the items that have been modified
to display a table.

Test plan:
0. Create at least one list (virtual shelf)
1. batch update biblios
2. Go to the job detail
3. Notice that dropdown list to add the record to a list
=> No regression found!
