LP1809157 SMS Carriers display not in alphabetical order

This alphabetizes the carrier display when editing the sms carrier in an existing hold.

It also adds the region to the name to make the interface consistent with other interfaces.

To Test:

1. Enable SMS options in the Library Settings.
2. Place a hold for a patron.
3. Use the Edit Notifications Settings.  Enter an SMS number, if needed.
4. Drop-down the Carrier list - the list is not in alphabetical order.
5. Apply the patch and repeat 3-4.
