This is not what node2nix does. Node2nix completely replaces `npm`'s
dependency resolution, therefore it is very dependent on the implementation
of npm. If instead, we would let npm do the resolution but make it do it
determistically by letting it resolve against the same npm index state we
wouldn't have that problem.
