Reviewed Additional Javascript Tests

@clarkbarz reviewed the javascript tests in pull request #128, which was requested in #127. 
remove this assertion and the compareModel because the attributes are sort of implementation details.

The getTemplate function is actually only used in one place, and it's something of a relic.  We used to have a stupid idea about caching the templates that is no longer in use.  If you just make sure that this works, then we should be good:

```javascript
templates.getTemplate('1').then(function(template) {
  assert.equal(template.get('template'), simulatedAjaxResponse['template']);
});
```

The render method is not even used anywhere.
