title: There are no commands defined in the "backup" namespace
body: <p>I have tried installing Laravel Backup for Database <a href="https://github.com/paulvl/backup" rel="nofollow noreferrer" title="paulvl/backup">paulvl/backup</a></p>
  
  <p>I have followed the instructions on how to install and configure it to my Laravel application. I am however stuck at the point where you actually run the backup command. I get this error: </p>
  
  <pre><code>$ php artisan backup:mysql-dump               
  [Symfony\Component\Console\Exception\CommandNotFoundException]
  There are no commands defined in the "backup" namespace.
  </code></pre>
  
  <p>Any help would highly be appreciated</p>
  
  <p>Here is the provider array in config/app.php
