Bug 28520: Revert "Bug 12362: Cancel transfer with hold cancelation"

This reverts commit 6c105829144cd341a4bc65ad8d0ee1f996b423d4.

This commit was part of a series adding adding reverse transfers, i.e.
transfers that were created for transfers that were cancelled and
we wanted the item to return back to its sending library. This however
hid the information about transfer happening and we need another approach
to the problem.
