Refactor rest\Functional\ResourceTestBase to use ApiRequestTrait

Please review MR!9059

Refactor appears fine.

Do we need a separate trait? Can we just say

  use ApiRequestTrait {
    makeApiRequest as request;
  }

directly in ResourceTestBase?

Assuming since JsonApi and LinksetController do the same that's why it was done that way.

@longwave Yes we can do that and actually I was planning to do the same but as @smustgrave mentioned I had taken the reference from jsonApi and linksetController.

More simpler without extra trait file

Haven't looked but may be worth a novice follow up to see if the other instances in jsonApi and linksetController could be refactored too?

But change here LGTM.

Committed e4d0bea and pushed to 11.x. Thanks!

As it's just a cleanup I don't see the point in backporting any further.
