title: False "missing route" inspection in PhpStorm w/ Symfony2 plugin
body: <p><strong>Background</strong></p>
  
  <p>One of the features of the Symfony2 plugin in PhpStorm is that it becomes aware of your routes, allowing for auto-completion and things like that.</p>
  
  <p>However, right now, my plugin seems to believe that the route does NOT exist, when it does. See attached images:</p>

  <p>For reference, here is the route debugger at work.</p>

  <p><strong>Question</strong></p>
  
  <p>Can this inspection be made aware of the routes?</p>
  
  <p><strong>Extra notes</strong></p>
  
  <p>This problem has existed for a while, both with and without a fresh cache.</p>
