Fix fetching via ssh

Before, the return value of fetchFrom: was used to checkout the default branch when cloning.
Since dcc1389, this is only needed for the internal implementation,
so the return value is not needed for the general fetchFrom: anymore. This allows us to not return the
refs when fetching externally, fixing fetching via ssh.
