title: Disable icon colorStateList in NavigationView
body: <p>In my app today I have icons which doesn't just have a single color, but in some cases two colors depending on the data state in my app. This means I can't use the default tinting behavior in <code>NavigationView</code>.</p>
  
  <p>It looks like with the new <code>NavigationView</code>, unless I specify a <code>ColorStateList</code> for my icons used in the list, a default <code>ColorStateList</code> will be made for me which uses my <code>colorPrimary</code> etc defined in my theme. </p>
  
  <p>Is there no way for me to force NavigationView to stop tinting my icons?</p>
