Backport r18516: Ensure call numbers are returned to the holdings editor in ascending sorted order
James Fournie in https://bugs.launchpad.net/evergreen/+bug/635121 reported
that call numbers were being displayed in the order that they had been
added to the database, rather than in sorted call number label order.
Although I have been unable to reproduce this problem on two different
test systems, the patch he provided for 1.6.1 (which fixes the problem on their
test system) shouldn't hurt other systems.
