Bug 22896: Missing inputs in transfer modal

This patch restores hidden inputs to save overridden checkin date and other data

Currently we lose the list of checkouts and several settings when items with transfers are checked in

To test:
1 - Find an item from another branch
2 - Set a checkin date and click the box for the date to be remembered
3 - Check in the item
4 - Click ok or print, note the checkin date is lost
5 - Apply patch
6 - Repeat
7 - Checkin date remains
