I realized it was checking NAR hashes before of added objects, which makes little sense --- we don't really care about ancillary NAR hashes. Now, the bottom `nix store add` tests compare the CA field with a git hash to hashes calculated by Git. This matches top `nix hash path` ones in using git as a source of truth.
