test-run-tests: do not rebuild hg in the test
d600bda4 and fc0f3ed0 added code to call `$PYTHON run-tests.py ...`. That
will rebuild hg, is slow and could have other crashes from setup.py, like:
Unable to find a working hg binary to extract the version from the
repository tags
Therefore use `run-tests.py -l` instead.
