Sorting files while extracting translation messages from a twig templates

Hello
When we generate a translations via command:
```php
app\console translation:update
```
is nice if order of found items don't change over the time (inside the file).
So we need to sort the *.twig files to prevent changes in output lang files.

This very simple fix do this.

Please consider this in your code :)

Thanks
