bug 9916: (follow-up) restore default sort order for self-check loan list

To test:

[1] Log into web-based selfcheck.
[2] Enter the barcode of a patron that has at least two loans.
[3] Verify that the loan list sorts them in order of descending
    due date by default, with a secondary sort order of ascending
    title.
