Pagination in graphql streams seems broken

[laurentS]

When running the tap on the dependencies stream, it enters an endless loop which seems to be caused by an invalid pagination logic. From the logs (only the last field differs):

2022-11-10 16:12:28,891 INFO METRIC: {"metric_type": "timer", "metric": "http_request_duration", "value": 2.874029, "tags": {"stream": "dependencies", "endpoint": "", "http_status_code": 200, "status": "succeeded", "context": {"org": "mapswipe", "repo": "mapswipe", "repo_id": 68943183, "per_page": 100, "nextPageCursor_1": "Mg"}}}
2022-11-10 16:12:31,102 INFO METRIC: {"metric_type": "timer", "metric": "http_request_duration", "value": 2.148324, "tags": {"stream": "dependencies", "endpoint": "", "http_status_code": 200, "status": "succeeded", "context": {"org": "mapswipe", "repo": "mapswipe", "repo_id": 68943183, "per_page": 100, "nextPageCursor_1": null}}}

Those 2 messages keep repeating until the tap is killed.
