bundle-tests: operate from outside a repository

We are about to add a test for ssh pull/cloning being denied because of bundle1
usage. For this, it is cleaner to not operate from the clone using http. So we
update the test beforehand for clarity. This is more churns that what I'm happy
to see on stable, but the rests of the series is worth it in my opinion.
