GX-Entwicklung

During the implementation of the background option to the section content, in the SE4, we changed the structure of the content zone HTML file.
We need to change it also for the all the default content zone files and fix the unit tests.

The changes must be made on Honeygrid and Malibu themes.

Before was:

<div class="container">
    <div id="textbox-4hhklyavl" class="gx-content-zone-row row textbox-g5ugj4ytx">.........</div>
</div>

Change to:

<div id="textbox-4hhklyavl" class="row textbox-g5ugj4ytx"> <!--  <--- NEW DIV -->
    <div class="container">
        <div class="gx-content-zone-row">.........</div>
    </div>
</div>
