Bug 26510: Transport Cost Matrix editor doesn't show all data when HoldsQueueSkipClosed is enabled

If HoldsQueueSkipClosed is enabled, and a library happens to be closed
on the day you edit the transport cost matrix, all the values for that
library will not show. Instead they will appear disabled, and if you
were to edit the cell and save a new value in it, it will also
'disappear' when the page is reloaded.

Test Plan:
1) Set today as a holiday for a library
2) Set HoldsQueueSkipClosed to 'open'
3) Go to the transport cost matrix editor
4) Edit a cell where the 'from' is for the closed library
5) Note the value doesn't 'save', it is still in the database though
6) Apply this patch
7) Restart all the things!
8) Reload the transport cost matrix editor
9) The value now appears correctly!
