title: Changes of Article.availableFrom in ShopWare has no effect
body: <p>i opend the Shopware 5.4.6 backend and</p>
  
  <p>set shop in <strong>edit mode</strong> (not productive mode). 
  i Checked in <code>Settings &gt; Performance</code> &#x2714; <code>Use shop in edit mode</code></p>
  
  <p>then i opend  <code>articel &gt; overview &gt; multichange</code>
  and set <strong>Article.availableFrom</strong> for all products to
  <strong>2018-10-10 00:00:00</strong>.</p>
  
  <p>These changes of the Article.availableFrom I find over the following Select:</p>
  
  <pre><code>SELECT distinct available_from, changetime, datum FROM s_articles
  2018-10-10 00:00:00, 2018-09-11 00:00:00, 2017-10-05
  </code></pre>
  
  <p>but the page reload (Shirt+F5) still shows:</p>
  
  <p><code>This article will be published on</code> <strong>October 11, 2018</strong></p>
  
  <p>That's why I tried the following (always followed by Themes compile and Web-page reload) in <code>Settings &gt; Theme Manager</code>:</p>
  
  <ol>
  <li>Compiler Caching deactivate OFF to ON</li>
  <li>CSS komprimieren ON to OFF</li>
  <li>JavaScript komprimieren ON to OFF</li>
  </ol>
  
  <p>And <em>checked all</em> in <code>Settings &gt; Performance &gt; Cache</code> and pressed the button <strong>Empty</strong> (followed by then Web-page reload Shift+F5)</p>
  
  <p>After all date i tried <code>Themes compile</code> and the i renamed the </p>
  
  <p>then i renamed <code>/var/cache/production_201807181357</code> to
  <code>/var/cache/backup_roduction_201807181357</code>
  After that, SW has created a similar folder. My problem persisted.</p>
