When recursively cloning a repository with a non-default ref storage format, e.g. by passing the `--ref-format=` option, then only the top-level repository will end up will end up using that ref storage format. All recursively cloned submodules will instead use the default format. While mixed-format constellations are expected to work alright, the outcome still is somewhat surprising as we have essentially ignored the user's request.
Fix this by propagating the requested ref format to cloned submodules.
