Bug 14297: Holds Queue building ignoring holds where pickup & home branch don't match and item is not from least cost branch

If a record has a hold on it where the pickup and home branch do not
match, the holds queue builder will only look at items from the least
cost branch ( as defined by the transport cost matrix or the sys pref
StaticHoldsQueueWeight.

Test Plan:
1) Create a record with two items, one for library A and one for library B
2) Set your circulation rules such that the book from library A is
   holdable by all and the book from library B is holdable only by library
   B patrons
3) Create a hold for a Library C patron for pickup at library C
4) Set the syspref StaticHoldsQueueWeight to by Library B, Library A,
   Library C in that order
5) Rebuild the holds queue
6) Note the hold wasn't picked up even though the item from library A
   could have filled the hold
7) Apply this patch
8) Rebuild the holds queue
9) View the holds queue again
10) Note the hold now displays
