Bug 24598: Complete transfer for hold if checked out

When an item that has triggered a hold is in transit to a library,
if the item is accidently shelved instead of scanned at the pickup library,
and then checked out to another patron, the holds shows the item still in transit
in the status, but says that it is waiting at the library, and the since date has vanished!

Test plan:
1) Place an item at Library A on hold for Patron 1 of Library B with pickup library at Library B
2) Check in the item at Library A to trigger the hold transfer
3) At Library B, check out the item to Patron 2 (click Yes)
=> The hold is not marked as in transit and is back to priority 1
