[kacurez]

https://keboola.atlassian.net/browse/ST-2131
Stop pagination if response contains empty data but still returns next page url.
This only works if query has enabled "stop-on-empty-response": true.
queries example with stop-on-empty-response enabled

    "queries": [
      {
        "id": 96947,
        "type": "async-insights-query",
        "name": "test",
        "run-by-id": false,
        "query": {
          "stop-on-empty-response": true,
          "parameters": "fields=ad_id,ad_name,impressions,reach,clicks,spend&level=ad&action_breakdowns=action_type&date_preset=last_month&time_increment=1",
          "ids": "",
          "limit": "25"
        }
      }
    ]

test case 1 - if stop-on-empty-response is enabled and data in the reponse is empty (mocked as :data []) then return nil, and pagination will consequently stop

test case 2 - if stop-on-empty-response is enabled and data in the reponse is not empty (mocked as :data [{:some "data"}]}) then return someurl, and pagination will continue.
