title: omnilight/yii2-scheduling doesn't give any output
body: <p>I'm using the plugin <a href="https://github.com/omnilight/yii2-scheduling" rel="nofollow noreferrer">omnilight/yii2-scheduling</a>. When I'm just executing their commands using terminal in ubuntu, I get no output. Commands I'm executing : </p>
  
  <pre><code>php /somepath/vendor/yiisoft/yii2 yii schedule/list
  php /somepath/vendor/yiisoft/yii2 yii schedule/run --scheduleFile=@app/config/schedule.php 1&gt;&gt; /dev/null 2&gt;&amp;1
  </code></pre>
  
  <p>Even I'm using their command for cronjob</p>
  
  <pre><code>* * * * * php /path/to/yii yii schedule/run --scheduleFile=@path/to/schedule.php 1&gt;&gt; /dev/null 2&gt;&amp;1
  </code></pre>
  
  <p>I'm not getting any output (Keep in mind that I'm not using any extension command to make it output the result into any file-by this it should give me output plainly then and there - right ?). Please advise where the problem lies.</p>
