Harden the tests (#237)

- Fix the coverage of some files (whitelist the files that should not be covered)
- Make `MapFile` return the unchanged path if no mapping is found for the given path: this allows to simplify some code
- Update the `ComposerOrchestrator` to not change the original `vendor/autoload.php` file if not necessary and make the changer prettier and more accurate (pure styling, no semantic change) when the file is changed
- Remove the config JSON imports support
- Fix some typos
- Add a lot of tests and rework some
