Remove trailing semicolon from generated template.

This semicolon means that we cannot include a compiled template inline
within a class definition.

Specifically the following breaks (needed in Ember) with the semi-colon:

```javascript
export default Ember.HTMLBars.template(
 /* HTMLBars compiled template that has trailing semicolon as below*/
 ;
)
```
