Unregister a fullName

```javascript
var container = new Container();
container.register('model:user', User);

container.lookup('model:user') instanceof User //=> true

container.unregister('model:user')
container.lookup('model:user') === undefined //=> true
```

@method unregister
@param {String} fullName
