To test:
1 - Enable RealTimeHoldsQueue system preference
2 - Set UpdateItemLocationOnCheckin to _ALL_: CART
3 - Check in an item
4 - Check the background jobs - the RTHQ is updated
5 - perl -e 'use C4::Items; C4::Items::CartToShelf(##);' -- substitute the itemnumber from above
6 - Check the background jobs - no new update to RTHQ
7 - Confirm item was set back to correct permanent_location
