tests: cd to tempdir during setUp

Since we were running hg clone from the hgsubversion repo, we would
often pick up config settings from hgsubversion/.hg/hgrc, including
loading extensions.  This caused tests to fail for me when they
asserted that obsolete is disabled because I have evolve enabled in my
hgsubversion checkout.  This was probably decreasing the overall
stability of the test suite as well, since it meant that clones were
running with pretty much arbitrary configs settings.

Interestingly, the setUp was already keeping a record of the cwd
before creating the tempdir, and tearDown was already cd-ing back to
that directory.
