Bug 9786 - Holds to pull showing items not available

If an item is on hold and waiting for pickup, and another
hold is placed on the record, a hold to pull will show in the
Holds to pull report, even though there are no items that can
fill that hold request.

Test Plan:
1) Create a record with 1 item
2) Create 2 holds on the record
3) Fill the first hold
4) Check the Holds to pull report, it should show this record
5) Apply patch
6) Reload the Holds to pull report, it should no longer show this record
