Bug 16462 - Change default sorting of circulation patron search results to patron name

This patch changes the default sort of patron quick search results from
the circulation header search or when searching for a patron during the
hold process.

To test:

In Circulation:
- Perform a search by name for a patron which will
  return multiple search results.
- Confirm that the results are sorted by patron name.

In the catalog:
- Locate and place a hold on a title.
- When prompted to select a patron to place the hold for, perform a
  search by name which will return multiple results.
- Confirm that the results are sorted by patron name.

Followed test plan, works as expected.
