title: cart.phtml override issue
body: <p>I am trying to override <code>cart.phtml</code> from <code>checkout\cart.phtml</code>  using <code>local.xml</code></p>
  
  <pre><code>&lt;layout version="0.1.0"&gt;
      &lt;checkout_cart_index translate="label"&gt;
          &lt;reference name="checkout.cart"&gt;
              &lt;action method="setTemplate"&gt;&lt;template&gt;test/cart.phtml&lt;/template&gt;&lt;/action&gt;
          &lt;/reference&gt;
      &lt;/checkout_cart_index&gt;
  &lt;/layout&gt; 
  </code></pre>
  
  <p>override works fine but when i try to empty cart it always call my <code>cart.phtml</code> instead of <code>checkout\cart\noItems.phtml</code>.</p>
  
  <p>when my cart is empty then it looks like

  <p>Any help will be appreciated</p>
  
  <p>Thank you</p>
