Bug 40620: Holds Queue will assign to the lowest item number if multiple branches have the same transport cost 

To Test:
Before applying:
1. Turn on the UseTransportCostMatrix system preference
2. Create holds on a record with multiple items. (I used Lanark in KTD)
3. Set the item location to all be the same (I used MID)
4. Set the holds to pickup at Centerville, Fairfield, and Pleasant Valley
5. Set the transport cost matrix to
Centerville\fairfield 1
Centerville\Midway 1
Fairfield\Centerville 1
Fairfield\Midway 1
Midway\Centerville 1
Midway\Fairfield 1
Midway\Pleasant Valley 4

6. Build the holds queue (either turn on realtime hold queue and then edit the bib to update or run the cron on the command line)
7. Run a report: select * from hold_fill_targets where biblionumber=9 order by borrowernumber;
8. Rebuild the hold queue
9. Run the report again, the results should be the same.

10. Apply the patch
11. Run the hold queue again
12. Observe the results should now be different.
13. Try a few more times and ensure the numbers are changing, create some more items at midway and try again to see more variety in numbers.
