Bug 12972 - Transfer slip and transfer message (blue box) can conflict

Instead of passing the homebranch to the slip, let's pass
TransferWaitingAt (the value we display)

To test:
1 - Check in an item that will initiate a transfer (hold or automatic
        item return)
2 - Note the transfer message and receipt match
3 - Remove the reason for transfer (bot don't cancel transfer)
    i.e. cancel hold or change homebranch of item to current library
4 - Check the item in again
5 - Note the message displays the transfer destination and the slip
shows the homebranch
6 - Apply patch
7 - Repeat 5 but note slip and message match
8 - Test any edge cases for correctness
9 - sign off
