Update class-aq-page-builder.php

On line 663 there was a "return" statement that finalized output before the remaining valid html could be rendered. Rather than use a "return" right there (it happens when no templates have been created and helps determine the contents of the "Add template" popup box), an "else" statement that specifically prevents the &lt;h3>, &lt;select>, and &lt;input> tags would probably work better.
