Bug 29103: Change desk when checking in a waiting reserve

A check in should relocate a waiting hold under the current desk. But
the current behaviour when confirming the hold is to dismiss the
modal, the item is still attached to the preceding desk.

This patch mimicks the print and confirm behaviour to trigger the desk
change.

Plan test:

1. Add some desks to you library (syspref UseCirculationDesks and
   Administration -> Patrons and circulation -> Circulation desks.

2. Set a desk in your session (Circulation -> Set library and desk)

3. Have some waiting hold attach to a desk (make a hold on a checked
   out item and return it).

4. Change your current desk.

5. Check in again the item, click on confirm.

6. Go to the item notice detail, it appears as waiting at your first
   desk.

7. Apply patch.

8. Check in again the item.

9. go to the item notice detail, it should appear at your current
   desk.
