Meaning indexes produced at the same nixpkgs commit always result in the database with identical checksum. This resulted in non-toplevel attrs being absent from the index but they are not useful for use cases like "comma", command not found handlers.
When running nix-index on old nixpkgs, scopes like rPackages are missing, so instead of exiting with an error, this change issues an error to stderr and skips such package set. Motivation: while it's possible to use an older version of nix-index to create the index for older nixpkgs, newer nix-index is much more performant so it's useful to be able to use it.
