next_jsonapi breaks jsonapi_defaults funcionality

[erikrau]

Package containing the bug

next (Drupal module)

Describe the bug

With the help of the jsonapi_defaults module (submodule of jsonapi_extras), you can add standard includes, filters, or sorting. The module changes the class definition for jsonapi.entity_resource. next_jsonapi also changes the class definition for jsonapi.entity_resource, which means that jsonapi_defaults no longer works.

Expected behavior

With next_jsonapi enabled I can also use jsonapi_defaults functionality.

Steps to reproduce:

1. First enable jsonapi_extras and jsonapi_defaults.
2. Then configure a resource e.g.: /admin/config/services/jsonapi/resource_types/node--article/edit
3. Add Default include list e.g.: uid
4. Visit /jsonapi/node/article and you will have user information included.
5. Enable module next_jsonapi.
6. Visit /jsonapi/node/article and you won't have user information included.
