scm: mercurial: update test repository for path encoding (#2664).

Mercurial (and also Git) treats file names as byte string.
This mercurial test repository contains Latin-1 encoding path.
Be careful on non Latin-1(CP1252) Windows.

If your Windows is not Latin-1 Windows,
in order to checkout(update) Latin-1 path,
You need to use cygwin 1.7 and set LANG=en_US.ISO-8859-1.

Please refer.

Redmine mercurial adapter do not need to checkout(update) repository.
Mercurial does not have "bare" repository such as Git.
You can use "hg update null" for equivalent "bare" repository.
