Bug 37378: libraries_where_can_see_things should always return an array
The subroutine libraries_where_can_see_things stores the list of libraries that things
can be viewed from in an internal variable, so we can return this directly if we have already calculated.
When returning if not cached, we dereference the list and return an array. If cached, we are returning
an arrayref. This patch simply ensures we dereference the array even if already cached.
Before this patch, we were fetching the patrons, then redacting all info as their branches didn't match against
an arrayref, rather than checking against each branch we are allowed to view.
To test:
1. Setup a library group and check the "Limit patron data access by group ." option.
2. Add some libraries to the group. ( IN k-t-d I added CPL and MPL )
3. Create a staff account who has staff access permissions and all of the borrower permissions except "view_borrower_infos_from_any_libraries"
4. Set the home library of that staff member to one of the branches in step 2. ( In my test I choose MPL )
5. Log in as that patron and attempt a patron search that would include users from either library in step 2.
6. See the error:
