Description

Configuration validation was throwing Symfony\Component\Debug\Exception\ContextErrorException caused by:

Notice: Array to string conversion in /Users/marek/workspace/gg/website/vendor/jms/translation-bundle/JMS/TranslationBundle/DependencyInjection/Configuration.php:84

in case provided provided dir is prefixed with not existing bundle.

Wrapping array_keys with implode(', ', ...) fixes the issue.
