Merge #973: Remove --features flag from sane just recipe

a572848 ci: remove `--features` flag from `sane` just recipe (nymius)

Pull request description:

  While executing `just sane` I received the following error message:
  
  ```bash
  cargo test --quiet --all-targets --no-default-features --features > /dev/null || exit 1
  error: a value is required for '--features <FEATURES>' but none was supplied
  
  For more information, try '--help'.
  error: Recipe `sane` failed on line 34 with exit code 1
  ```
  
  I removed the flag because if fixes the issue and the flag is not receiving a feature list.
