I fixed the Translator service argument for Translation Twig Extension, which was a bit hard to debug, because of `nullOnInvalid` and the anonymous class created in the Extension if Translator is null (https://github.com/symfony/symfony/blob/master/src/Symfony/Bridge/Twig/Extension/TranslationExtension.php#L50).
