Clear out existing virtualenv when creating
We check whether a virtualenv has been created successfully by the
spec file that is written after the virtualenv has been initialized
and the spec requirements installed. In the event that a previous run
failed before the spec file was written, we want to clear out the
partially created virtualenv and recreate it fresh.
