Clone repo from remote URL fails

[Thomas De Schampheleire]

Hello,

I now see:

kallithea_1  | Exception AttributeError: "'sshv1peer' object has no
attribute 'ui'" in <bound method sshv1peer._cleanup of

It's been a while that I tested this, but I wonder if it could be
related to a mercurial version? This instance is running 4.7.2.
In commit 03dfcbe52906 there has been a change in this area, but I
didn't investigate it further.

Any feedback is welcome,
Thomas
