LP#1712686 - display completed barcode on copy grids not partial input

The check in, check out, and renew interfaces were not displaying
the actual complete(d) barcode when barcode completion is on.
This saves the inputted partial barcode in row_item.input_barcode
and let's the returned acp.barcode be in row_item.copy_barcode for
display.
