Jonathan Druart 2bb09975bc Bug 5428: Jump back to the search result after deleting a record
This patch adds the ability to jump back to the search result after a
record has been deleted.
Also it keeps the "browser" when all items are deleted from a
bibliographic record

Test plan:
- Start a new search
- Select a record with items
- Delete all the items
=> You still see the browser
- Delete the record
=> You are back to the adv search form but we new link "Go back to the
results" is present at the top of the page

Limitation: As we delete the record we do not longer know the offset,
we are back to the first page of the result list
