Pagination goes into infinite loop when querying empty lists

When requesting a paginated resource with no values the paginator goes into an infinite loop of requests to the spotify api.

To reproduce the bug I made this query on a user with no public playlists

{
   user(id: "someid"){
    playlists{
      name
    }
  }
}

The api returns an empty list with total=0, but the !!iterator.total condition inside the shouldStopIterate function causes and infinite loop of requests.
