Ou setting cat.require_call_number_labels = FALSE does not work with multiple items

[Michele Morgan]

With cat.require_call_number_labels set to FALSE, a user can save items with blank call number labels if there is a prefix set.

When editing multiple items with call number prefixes and blank labels, the user cannot save the items. The Save buttons remain disabled.

We have noticed the same issue when editing *individual* items if these steps are followed in the angular holdings editor:

--Delete the existing call number
--Scan/enter a new barcode
--Apply a holdings template that includes a call number prefix

--Note that the "Apply/Save" buttons are inactive.

In order to save holdings in this scenario, it is necessary to edit the barcode or to enter (and immediately delete) a value in the call number field. These extra steps are inefficient and prone to error.

If the order of actions is changed to either of the following, the "Apply/Save" buttons are active:

--Apply a holdings template that includes a call number prefix
--Delete the existing call number
--Scan/enter a new barcode

OR

--Scan/enter a new barcode
--Apply a holdings template that includes a call number prefix
--Delete the existing call number

But, for some of our libraries, these are the most logical nor preferred order of actions.

Thanks to Jane Sandberg, here is a working branch that assures the ou setting is resolved before it's consulted:

We have tested this locally and it fixes the issue for us.
