tests: Skip tests if they will fail because of outer repo

For different reasons these tests will fail if run in a tmpdir which is in a hg
repo.

The following three tests assumes no .hg in path dirs - I don't know how to
work around that:

* test-dispatch explicitly tests for no repo and expects "abort: There is no
Mercurial repository here (.hg not found)!"

* test-extension expects parentui to be None when not cd'ed to a repo dir

* test-globalopts tests that implicit -R works correctly - that could perhaps be
done from another repo instead of assuming no repo

The following two might be worth investigating further:

* test-convert-svn-sink fails for unknown reasons, starting with "abort:
unresolved merge conflicts (see hg resolve)"

* test-glog gets strange failures when testing "from outer space"
