Bug 24171: Preserve auto_renew when triggering itemBarcodeFallbackSearch

Bug 24171: Preserve auto_renew when triggering itemBarcodeFallbackSearch

The auto_renew parameter is not sent to the template when the popup
triggered by itemBarcodeFallbackSearch is displayed.

Test plan:
- Turn on itemBarcodeFallbackSearch
- Open a patron account
- Check the checkboxes for automatic-renewal
- Search for a title keyword in the checkout input box
- Verify that auto-renewal flag is set

Note for QA: The auto_renew flag will be set in any cases. Should we
expect regression?
