title: Android <include> didn't work with ViewBinding
body: <p>I have an issue with this "new" Android View Binding. I get an exception when I try to use a   <code>&lt;include&gt;</code>
  in my XML-Layout file:
   <code>&lt;include layout="@layout/teaser_agreement" /&gt;</code> </p>
  
  <p>The include file is just a basic layout file. Everything works fine if I replace the <code>&lt;include&gt;</code> tag directly with the layout code which should be included.</p>
  
  <p>This is the exception from the generated class:</p>
  
  <pre><code>error: incompatible types: TeaserAgreementBinding cannot be converted to ViewDataBinding
          setContainedBinding(this.mboundView11);
  </code></pre>
  
  <p>Any suggestions?</p>
  
  <p>Thx,
  Mirco</p>
