title: Laravel Artisan Command show verbose error messages
body: <p>Typically I run a laravel artisan command like</p>
  
  <pre><code>php artisan Command -v
  </code></pre>
  
  <p>and if there is an error I can find the file/line#, using the -v flag.</p>
  
  <p>For some reason the -v is not working on one of my commands. I am therefore receiving a pretty limited error message:</p>
  
  <p><code>[Symfony\Component\Debug\Exception\FatalErrorException]
    Call to a member function getArgument() on null</code></p>
  
  <p>This command happens to be calling some code that is extending someone else's code. </p>
  
  <p>Any ideas how to get the file/line output in the error message?</p>
