    preview: Simplify the PreviewNavControls setModel code
    
    There is no need to mix setting the model and updating the visibility
    of the controls. Once a document has finished loading we set the model
    and call the show method to reveal the controls. When we leave the
    preview, we call hide or destroy the controls.
    
    This is made possible by consolidating the load-finished code in the
    previous patch.
