Describe the bug

A clear and concise description of what the bug is, including:

• Build system: x86_64-linux
• Haskell.nix rev: 8f6a720

When running nix flake check, I have encountered the error cannot coerce null to a string while checking a haskell.nix shell.
The cause is in shell-for.nix:61:

comp: selectedComponentsBitmap."${((haskellLib.dependToLib comp).name or null)}" or false;

I guess the fix would be

comp: selectedComponentsBitmap."${((haskellLib.dependToLib comp).name or "")}" or false;

(not sure)
