Bug 15062: Holds queue with Transport Cost Matrix will transfer item even if transfers disabled

If the transfer of an item from Library A to Library B is disabled in
the Transport Cost Matrix, but the only item on a record is from Library
A, the holds queue will request a transfer of that item from Library A
to Library B even though the rules state such a transfer is not allowed!

Test Plan:
1) Enable the transport cost matrix
2) For simplicity, leave all cells disabled on it, save this state.
   This state means that only items at each location should fill
   holds where the pickup library is that same location.
3) Create a record with one item, set its home and holding branch
   to Library A
4) Create a hold for pickup at Library B
5) Rebuild the holds queue
6) Note the transfer request for the item to Library B
7) Apply this patch
8) Rebuild the holds queue
9) Note the transfer request is gone
