LP1119370: Corrects sorting in the list of z39.50 services

To test
-------
[1] Add several z39.50 servers, with names starting with both
lower case and capital letters.
[2] In the Web client, go to Cataloging > Import Record from
Z39.50. The list of Services and Credentials will be sorted
in order alphabetically twice -- first for names that start
with a capital letter, then for names that start with lower
case letters.
[3] Apply this patch and repeat step 2.  This time, the list
should be sorted alphabetically, and then have Local Catalog
at the very bottom of the list.
