Bug 23987: "return to cataloguing" if the record is deleted from bachMod-del

Bug 23987: "return to cataloguing" if the record is deleted from bachMod-del

If a bibliographic record is deleted after having deleted all their items in a batch,
we should not display a "return to the record" button but "return to cataloguing" instead

Test plan:
1 - Have/make a bib with items
2 - On details page select Edit->Delete items in a batch
3 - Select all items and check "Delete record if no items remain"
4 - Delete the things
5 - On confirmation screen you have a count of items/bibs deleted
=> Without the patch there is a 'Return to record' button that leads to nowhere
=> With this patch there is a "Return to cataloging module" button
6 - Repeat using the "Delete selected items" link on top of the items table
=> Without the patch there is a 'Return to where you were' button that leads to nowhere
=> With this patch there is a "Return to cataloging module" button

Note that there is a link AND a button, coming from
  commit 928c0af2b6a2c7aa6ed54019c5bd7dbddbccf4ee
  Bug 15824 - 'Done' button is unclear on batch item modification and deletion
I do not think it makes sense to have both.
