LP#1980887: fixes cases where shelving location selector didn't work

This patch fixes an issue where the Angular shelving location selection
component (eg-item-location-select) wouldn't work (in particular,
when its contextOrgIds wasn't set, as opposed to contextOrgId).

Coding note: TypeScript confounds the Perl programmer: an empty array
evaulates to true; .length needs to be checked instead.

To test
-------
[1] Apply the patch.
[2] Verify that the shelving location selector works in the following
    interfaces:

    - Acquisitions Administration -> Distribution Formuals
    - Course Materials (in the material form for a course)
    - Linked locations for Circulation Limit Sets
