Allow actual overriding of JsonResource in collections

[xwiz]

When using Laravel, one has the option of using a custom resource class that extends JsonResource to transform resources in http requests.

If you try to override the other methods in the JsonResource class however, there's a 99% chance no other method you override will be called except toArray, the reason is because when the Router toResponse is called, it invokes a second toResponse on the AnonymousResourceCollection and ends up in a chain of original class calls where the actual collector class is never used albeit overriding JsonResource.

One possible approach is to invoke the actual resource collector from ResourceCollection

For example instead of:

  public function toResponse($request)
  {
      if ($this->resource instanceof AbstractPaginator || $this->resource instanceof AbstractCursorPaginator) {
         return $this->preparePaginatedResponse($request);
      }

     return parent::toResponse($request);
 }

We could have:

  $collector = new $this->collects($this->resource);
  return $collector->toResponse($request);

This way, users can benefit fully from http resources.
