Bug 16358: Do not redirect to the editor when deleting records

The "Delete record" button goes to addbiblio.pl?op=delete, which
incorrectly redirects to Rancor when selected.

Test plan:
0/ Enable EnableAdvancedCatalogingEditor
1/ Edit a record
2/ Switch to the Advanced editor
3/ click on "View the record"
4/ Delete the record
=> Without this patch you are redirected to the editor
=> With this patch you are redirected to the advanced search
