Does not annotate when name is variable

```js
let name = 'NotWorking';
app.controller(name, function ($http) { });
app.controller('works', function ($http) { });
```

Result
```js
var name = 'NotWorking';
// should have been annontated
app.controller(name, function ($http) {}); 
app.controller('works', ["$http", function ($http) {}]);
```
