Nixpkgs config is ignored

[expipiplus1]

To reproduce:

• Allow broken packages in `~/.config/nixpkgs/config.nix

  { nixpkgs.config.allowBroken = true; }

• Run cached-nix-shell -p haskellPackages.alga (or any other package marked as broken)

• Observe that the package doesn't built with the following error

$ cached-nix-shell -p haskellPackages.alga
cached-nix-shell: updating cache
error: Package ‘alga-0.2.2’ in /home/j/src/nixpkgs/pkgs/development/haskell-modules/hackage-packages.nix:25062 is marked as broken, refusing to evaluate.

a) For `nixos-rebuild` you can set
  { nixpkgs.config.allowBroken = true; }
in configuration.nix to override this.

b) For `nix-env`, `nix-build`, `nix-shell` or any other Nix command you can add
  { allowBroken = true; }
to ~/.config/nixpkgs/config.nix.

(use '--show-trace' to show detailed location information)
cached-nix-shell: nix-shell: exit code: 1

• Run nix-shell -p haskellPackages.alga and observe that the package builds correctly

This happens for allowUnfree too
