title: symfony doctrine:generate-migrations-diff not working
body: <p>I've tried on two separate development machines, but I can't get the doctrine:generate-migrations-diff to work.</p>
  
  <p>I keep getting the same error:</p>
  
  <pre><code>PHP Fatal error:  Class 'ToPrfxPage' not found in /private/var/folders/a1/a1HQHKvmG-4VtnVS-e4i1E+++TI/-Tmp-/toprfx_doctrine_tmp_dirs/ToPrfxLibraryPage.php on line 32
  </code></pre>
  
  <p>It looks like it's generating a temporary class that it's not able to load again. Is there a way to fix this?</p>
