Bug 37385: Fix Transfer not triggering automatically when cancelling a hold by checking in an item

Upadates for CSRF are inadvertently stopping AddReturn from being trigger
when a hold is canceled. This is necessary to generate the transfer
back to the originating library.

Test Plan:
1) Find item with a waiting hold, and check it in
2) In the popup notifying me of the waiting hold, select 'Cancel hold'
3) Note no second popup appears notifying you of the need to transfer the item to its home library
4) Apply this patch
5) Restart all the things!
6) Repeat steps 1-2
7) Second popup appears!
