FileTransfer: cancel a file transfer on A is not received on B

[erikos]

Steps to reproduce:

- open a file transfer on A for B

- on B do not accept/decline it

- cancel the file transfer on A using the option in the Palette in the activity tray

---> B should receive a notification that the file transfer has been canceled

I tested this as well on 0.84 as not working.

This seem to be an upstream bug:  https://bugs.freedesktop.org/show_bug.cgi?id=40861

There is as well the following bug  http://dev.laptop.org/ticket/11065 that let's you not remove the notification when a file transfer has been canceled.

We have been implementing the same behavior in Sugar now than what we empathy is doing: we do not get a direct notification that the transfer has been canceled but when we try to accept the transfer we get the notification.
