Bug 35432: Simplay HoldsQueuePrioritize branch check

The code here is going to check items held the the pickup location for a request
or from the least cost branch matching the patron's home library against the HoldsQueuePrioritizeBranch
setting

The loop is the same in both case, so lets simplify this a bit to make the intent more clear

To test:
1 - prove -v t/db_dependent/HoldsQueue.t
2 - It should pass before and after this patch
