cargoNextest and cargoTest silently do not run anything

[RossSmyth]

Describe the bug

There is no error message, since it's just bash it silently fails when something doesn't run.

If I look at the derivation outputs, there is a target.tar.zst and target.tar.zst.prev in the result directory and nothing else. Running cargo test normally works fine outside of Nix.

Things that work: cargoAudit, cargoClippy, cargoDeny, cargoBuild

Reproduction

I will try to do so when I get home.
