Comment 10 for bug 1856795

[Test case]
Connect to a x2go server on a session that has file sharing or audo-forwarding enabled -> Error message "SCP: Warning: status code 1 received: scp: ~<user>/.x2go/ssh: No such file or directory" needs to be clicked away with "ok".

[Regression potential]
Very low as the patch removes "~<user>" from the ssh string which is the same as just using no path spec (":") as the default is the home dir of the logged in remote user.

I have tested Graham's ppa packages and they work again as before the libssh change and fix the bug reliably.
