Run preprocessors in `mdbook test`
While adding support for translations[1] to Comprehensive Rust 🦀, I noticed that `mdbook test` doesn’t execute preprocessors the same way as `mdbook build`. This PR makes the two commands use the same code to find and execute preprocessors. [1]: https://github.com/google/comprehensive-rust/pull/130
