hg: fix URL cloning with Mercurial 4.6 and later In 03dfcbe52906, I didn't notice that the API also changed ... and it was not sufficiently tested. Now, instead of using the peer classes directly, use the instance wrapper. There is no automated testing of this, but it was tested manually to also work in the oldest supported Mercurial version.
