* Fix clippy lints in tests * CI: let clippy lint also tests They deserve equal clippy love, right? :)
* Tidy code a bit thanks to clippy Clippy 1.54 newly detects some redundant constructs, that's nice. sort_unstable() should yield exact same results as sort() for `Vec<&str>` and could be faster, clippy says. * Add clippy to CI
