Bug 12362: Cancel transfer with hold cancelation

This patch adds a transfer cancellation when a hold is cancelled.

Test plan
1/ Check an item out from it's homebranch
2/ Place a hold on that item for another user at a different branch
3/ Check the item in at it's homebranch and accept the transfer
4/ Cancel the hold
5/ Change to the second branch and check the item in
6/ Note that a transfer is triggered with the reason 'Transfer was
cancelled whilst in transit'
