disable the deprecated sensio_framework_extra.router.annotations

fixes #786

`famework.annotations` still needs to be true due to the `validation: { enable_annotations: true }` in `framework.yaml`.

Should I move the `framework.annotations: true` to the `framework.yaml` file instead? It seems more appropriate.
