title: Error when querying for records in ember.js when using FixtureAdapter
body: <p>I'm trying to retrieve a value from a model from another page in the <code>model()</code> function of a route. This works fine when I look up the record by ID:</p>
  
  <pre><code>self.store.find('thing', 1).then(function(beers) { 
      self.controllerFor('edit').set('title', beers.get('beer'));
  });
  </code></pre>
  
  <p>However, when I try to use a query to get this, I get a <code>Error: Assertion Failed: Error: More context objects were passed than there are dynamic segments for the route: error</code> message from line 14261 of ember.js.</p>
  
  <p>Here's the code that causes the issue:</p>
  
  <pre><code>self.store.find('thing', { beer: params.beer }).then(function(beers) { 
      self.controllerFor('edit').set('title', beers.objectAt(0).get('beer')); 
  });
  </code></pre>
  
  <p>I've ensured that the model has the section property and that params.section is being set properly from the route. What would be causing the error? The problem is demonstrated in <a href="http://emberjs.jsbin.com/wikayaqupi/1/edit?js,output" rel="nofollow">this bin</a>.</p>
