template was modified to search first in the $templateCache.

some template use to preload from markup
```
	<script type="text/ng-template" id="cell-thumbnail.html">
		<img src="{{row.getProperty('thumbnail')}}" width="30px" height="30px"><span>{{row.getProperty('from')}}</span>
	</script>

```

text/ng-template load into $templateCache.
so i changed to search first in the $templateCache.
