When an existing `headRepo` couldn't be detected, it's time to auto-fork one. Unfortunately, an obscure Go behavior made it seem like `headRepo` was a non-nil value, where in fact it did contain a nil pointer which would crash the process. This avoids ever assigning nil pointers to `var headRepo ghrepo.Interface`.
