title: OroPlatform without any entity alias
body: <p>My OroPlatform-based system has no registered alias. </p>
  
  <p>When I enter the command <strong><em>php bin/console oro:entity-alias:debug</em></strong> in the terminal, it returns only the result below:</p>
  
  <pre><code>Class Alias Plural Alias
  </code></pre>
  
  <p>Does anyone have any idea what may have made all entity alias disappear?</p>
