title: How to change asset publisher default not found message?
body: <p>I have a <code>asset-publisher</code> of news/articles, but when I enter the name of a non-existent article in the friendly URL it appear wrong message.</p>
  
  <p>Friendly URL:</p>
  
  <pre><code>/-/asset_publisher/instanceID/content/name-of-non-existent-article
  </code></pre>
  
  <p>Error message:</p>
  
  <blockquote>
    <p>El usuario no existe.</p>
  </blockquote>
  
  <p>Translated:</p>
  
  <blockquote>
    <p>The user could not be found.</p>
  </blockquote>
  
  <p>Literally translated:</p>
  
  <blockquote>
    <p>The user does not exist.</p>
  </blockquote>
  
  <p>But as i said my <code>asset-publisher</code> is of articles/news and not of users.</p>
  
  <p>Is there a way to change this message? </p>
  
  <p>Or maybe i need to specify the content type? How?</p>
  
  <hr>
  
  <p>I wont to hook that property:</p>
  
  <pre><code>the-user-could-not-be-found=The user could not be found.
  </code></pre>
  
  <p>That was not the key to hook (i was looking another version properties), look at answer.</p>
