title: dependency on a non-existent service "doctrine.orm.default_entity_manager"
body: <p>I am using JMSPaymentCoreBundle and JMSPaymentPaypalBundle.</p>
  
  <p>It worked well before,but now I have to change my config.yml for new Bundle(FOSMessageBundle)</p>
  
  <p>I have to stop using 'auto_mapping' and  use 'entity_managers' instead</p>
  
  <pre><code>doctrine:
      dbal:
  
      orm:
          auto_generate_proxy_classes: %kernel.debug%
  #       auto_mapping: true
          entity_managers:
              FOSUserBundle: ~
              FOSMessageBundle: ~
  </code></pre>
  
  <p>However after this changes .</p>
  
  <pre><code> The service "payment.plugin_controller" has a dependency on a non-existent service "doctrine.orm.default_entity_manager"
  </code></pre>
  
  <p>this error happens.</p>
  
  <p>I think changes in config.yml causes this trouble.</p>
  
  <p>How can I solve this problem?</p>
