The commit php-cs-fixer broke some steps definition in a few contexts.
The rule doctrine_annotation_spaces remove spaces around parentheses for Doctrine annotations but it works with a blacklist which is not including Given, When and Then.

It also introduced the declare(strict_types=1); which generates error in multiple places.
For instance in the DebugContext there is:

$featureName = urlencode(str_replace(' ', '_', $scope->getFeature()->getTitle()));

But getTitle returns string|null because the title is optional, which generates TypeError exceptions hiding the real failure of the test.
In Asserter::assertContains() we use preg_quote to perform the check but the expected value could be something else than a string and tests fails even though they were passing before.
