missing space in check-out's 400 message

*Overview:*A failed call to /circulation/check-out-by-barcode returns an error like,"Temeraire (book) (Barcode:653285216744) has the item status Intellectual item and cannot be checked out".There is a missing space after the colon and it's driving me bonkers.

Steps to Reproduce:

1. Create a non-loanable item
2. Attempt to check it out

Expected Results: An error message containing, "...(Barcode: 653285216744)..."
*Actual Results:*An error message containing,"(Barcode:653285216744)"
