Bug 11475: fix return link after editing/deleting items in batch

Bug 11475: fix return link after editing/deleting items in batch

Bug introduced by bug 9044.

Test plan:
1- First we search for records with multiple items (books or serials,
does not matter)
2- We open this record we found with multiple items for editing
3- We chose "Edit items in batch" option from the "Edit" menu
4- We make corrections on the fields under the "Edit item"  (For example
we change the collection code as "fiction")
5- We save this using "Save button" at the bottom, after we are done.
6- Just after we save, there will be a button named "Done" available
just under the page, and when we click on "Done" we encounter the Error
screen.

Before the patch, the "Done" link points to
/cgi-bin/koha/tools/CATALOGUING.
After applying the patch, the "Done" link points to the biblio detail
page.
