Bug 9724: ensure hourly loans show time due in SCO

Due dates in the self checkout module don't display the time items are
due, and thus items which are on hourly loans don't display an accurate
due date and time. This patch corrects this by adding the "as_due_date
=> 1" parameter added by Bug 9723.

To test, apply the patch for Bug 9723 if necessary. Enable an hourly
loan period for an itemtype in your collection. Log into the
self-checkout system and check out an item which circulates by the hour.
The due date and time should be displayed correctly.

Check out an item which does not circulate hourly. The due date should
be displayed as a date only.

Test in both prog and Bootstrap themes.

Followed test plan. Works as expected.
