Bug 28520: Revert "Bug 12362: (QA follow-up) Fix ModItemTransfer cancellation handling"

This reverts commit fbba09f63f200d3e57a8612554984d807867cf84.

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.
