Do not require data-init attribute if a template has been specified

[ErikSchierboom]

At the moment, you have to do this:

<ul data-bind="foreachInit: { name: 'personTemplate', data: persons }">  
  <li data-init data-bind="init, text: name">Michael Jordan</li>
  <li data-init data-bind="init, text: name">Larry Bird</li>
  <li data-init data-bind="init, text: name">Magic Johnson</li>
</ul>

<script type="text/ko-template" id="personTemplate">
  <li data-template data-bind="text: name"></li>
</script>

However, as the template has been explicitly specified, the data-init attribute is not necessary. You should be able to do this:

<ul data-bind="foreachInit: { name: 'personTemplate', data: persons }">  
  <li data-bind="init, text: name">Michael Jordan</li>
  <li data-bind="init, text: name">Larry Bird</li>
  <li data-bind="init, text: name">Magic Johnson</li>
</ul>

<script type="text/ko-template" id="personTemplate">
  <li data-template data-bind="text: name"></li>
</script>
