title: Discord.js unable to login after using Client#destroy()
body: <pre class="lang-js prettyprint-override"><code>switch (command[0])
  {
    case 'restart':
      if(msg.author.id == config["owner"]){
        msg.channel.send(preEmbed('clientRestart'));
        client.destroy();
        client.login(config["token"]);
      }
      break;
  }
  
  </code></pre>
  
  <p>this causes the error <code>DiscordjsError: Request to use token, but token was unavailable to the client.</code></p>
  
  <p>anyone know the cause / fix?</p>
