Title: Remove reassignment on extend

I think I originally put the reassignment in there as I failed to recognise that the most common use case would require re-sharing the extended service, and thought people would just be able to do:

```
$app->extend('twig', function ($twig) {
```

I think we should take the opportunity of 2.0 to remove the reassignment.
