Bug 23007: Retain focus on 'barcode' input if transfers don't block circ

To test:
 1 - Apply patches
 2 - Update database
 3 - Confirm TransfersBlockCirc defaults to 'Block'
 4 - Check in an item that needs transfer
 5 - Confirm you must deal with the modal to proceed
 6 - Repeat checking to get 'wrong-transfer-modal'
 7 - Confirm you must deal with it to proceed
 8 - Switch the pref to 'Don't block'
 9 - Find a new item or cancel/fulfill the preceeding transfer
10 - Check in the item to generate transfer
11 - Note focus remains on the barcode field and you can continue scanning (or typing if you don't have a scanner)
12 - Note typing and pressing enter continues without requiring you to deal with modal
13 - Repeat for wrong transfer modal
14 - Verify hold and other modals still block continuing circulation
