title: symfony4 migrate autowire to true - get error message
body: <p>I am migrating from symofony 2.7 to symfony 4.0. With success I migrated one bundle. Now I am migrating the second bundle and the error message is coming up. I don't get at all what symfony 4.0 wants from me. </p>
  
  <p>If I turn on <code>autowire: true</code> this error message is coming up.</p>
  
  <pre><code>Cannot autowire service "App\Kernel": argument "$environment" of method "Symfony\Component\HttpKernel\Kernel::__construct()" must have a type-hint or be given a value explicitly.
  </code></pre>
  
  <p>Can somebody help me?</p>
  
  <p>If I turn it off, no message is coming up. </p>
  
  <p><strong>Update</strong></p>
  
  <p>I registered my bundle only in bundles.php</p>
  
  <pre><code>App\Backend\AccountBundle\BackendAccountBundle::class =&gt; ['all' =&gt; true],
  </code></pre>
