title: Handlebars link-to helper with Bootstrap navbar
body: <p>I found a post on here that said in order to use Twitter Bootstrap's navbar with Ember and Handlebars, so that the <code>&lt;li&gt;</code> gains the 'active' class automatically, I could do this:</p>
  
  <pre><code>    {{#link-to 'dashboard' tagName="li" href=false}}
          {{#link-to 'dashboard'}}
              Dashboard
          {{/link-to}}
      {{/link-to}}
  </code></pre>
  
  <p>It works, however, I've just enabled Ember's LOG_TRANSITIONS and it shows me that the views are getting transitioned to twice for the links in the navbar.</p>
  
  <p>How do I correctly render the navbar list with Handlebars and avoid this double loading?</p>
