removed deprecations in symfony 3.4:

[ziegler-b5c]

DependencyInjection/JMSJobQueueExtension.php: The type "jms_job_safe_object" was explicitly marked as commented in its configuration. This is no longer necessary and will be removed in DoctrineBundle 2.0. Please remove the "commented" attribute from the type configuration.

Controller/JobController.php: The "Sensio\Bundle\FrameworkExtraBundle\Configuration\Route" annotation is deprecated since version 5.2. Use "Symfony\Component\Routing\Annotation\Route" instead.

Symfony\Component\Routing\Annotation\Route already exists in 2.0 so no problem!
