When the path given to 'git submodule add' is an existing repository that is not in the index, the repository is passed to 'git add'. If this repository doesn't have a commit checked out, we don't get a useful result: there is no subproject OID to track, and any untracked files in the sub-repository are added as blobs in the top-level repository. To avoid getting into this state, abort if the path is a repository that doesn't have a commit checked out. Note that this check must come before the 'git add --dry-run' check because the next commit will make 'git add' fail when given a repository that doesn't have a commit checked out.
