Bug 22877: Prevent double overdue processing for lost and returned

Test plan:
1 - Issue an item to a patron with a backdated due date
2 - Run fines.pl - note you generate a fine for the patron
3 - Run longoverdue.pl - make sure MarkLostItemsAsReturned is turned off
and to charge
4 - Confirm the patron has a lost fee and an overdue
5 - Return the item
6 - With patch applied, patron should now have 1 overdue fine and 1 lost fine
