Composer update - Be careful to yaml version - Environnements menu disapears

[JacquesJahnichen]

Hello,

To update codeception to 2.3.* you have to update symfony/yaml. But on Webception front end the "Environnements" menu disapears when you update "symfony/yaml" around 3.4.

Here is the configuration you have to keep on your composer.json

    "require": {
        "php": ">=5.3.0",
        "slim/slim": "2.*",
        "slim/views": "0.1.*",
        "twig/twig": "~1.13",
        "codeception/codeception": "2.3.*",
        "symfony/yaml": "2.7.x-dev"
    },

This helped me because webceptions codeception dropped this: Call to undefined method AcceptanceTester::seeInDatabase

After updating everything is fine.
