Bug 18284: (bug 17196 follow-up) Move biblio metadata when a biblio is deleted

There is a deletedbiblio_metadata table but it is not populated when a
biblio is deleted. Since we have a ON DELETE constraint on
biblio_metadata.biblionumber, the row is deleted when the biblio entry
is deleted => data lost!

Test plan:
- Create a biblio
- Delete it

=> Without this patch the deletedbiblio_metadata table is not populated
with the biblio_metadata row related to the biblio

=> With this patch applied you should see that the row has been moved.

Followed test plan, behaves as expected
