test: don't empty HGRCPATH

Extensions can't interfere, because we need to enable them in our hgrc,
which we specify manually so no other hgrc interferes.

This would allow to test that HGRCPATH is working properly inside
gitifyhg.py, if it decides to read the configuration using the
heuristics of Mercurial (see git-remote-hg for reference), or that it's
properly isolated from a real environment that, which would need a
separate test that pollutes ~/.hgrc.

gitexporter: remove quote marks from paths (#83)

Paths with whitespace seem to come from git enclosed by quotation marks,
which were being passed on to Mercurial.  Explicitly remove these enclosing
quote marks so that Mercurial doesn't include them; other quote marks are
left in (as they are likely desired).
