Enable compiling the workspace with --tests --all-features

[mirgee]

A hotfix to enable compiling the workspace with --tests --all-features.

It is recommended that

[...] features should be additive. That is, enabling a feature should not disable functionality, and it should usually be safe to enable any combination of features. [...]

meaning the code should compile with all features enabled as well.

(Selfish reason is that I am using these cargo options in the rust-analyzer settings globally to enable code completion and error / warnings hints in any Rust project in all code, including code compiled conditionally using features and all tests. If the workspace stops compiling before it reaches the code I am working on, I get no error hints.)
