Test plan with KTD:
- Issue a couple of items to a patron, and make sure one of them is
  overdue.
- Make sure "Always show checkouts automatically" is not checked
- Reload the page
- Click on the link in "Overdues: Patron has ITEMS OVERDUE See
  highlighted items below"
- Nothing happens
- Apply the patch, restart_all, reload the "Check out" page for the
  patron
- Click on the link again, and the active loans should be shown
