Bug 18534 - When IndependentBranches is enabled the pickup location displayed incorrectly on request.pl

To recreate:
1 - Place a hold for pickup at Midway
2 - Enable independentbranches
3 - Login to staff interface as admin without superlibrarian status from
a different branch
4 - View the holds for the title you placed a hold on
5 - The hold placed in step 1 should show a dropdown with current branch
as pickup location, current branch is the only in that dropdown
6 - Verify it displays correctly for superlibrarian
7 - Apply patch
8 - The correct pickup location should show and not be editable
9 - Verify it is a dropdown
