Bug 19053: Keep auto_renew flag if a confirmation is needed

If an item is checked out with the auto renewal flag and a confirmation
is needed (holds exist, past due date, etc.) the auto renewal flag will
get lost.

Test plan:
- Check an item out and specify a past due date
- Confirm the checkout on the confirmation screen
=> Without this patch the checkout is not marked as auto renewal
=> With this patch applied the auto renewal flag will be set to the
checkout
