/**
 * Some “list” response that can be paginated have a different response structure
 *
 * They have a `total_count` key in the response (search also has `incomplete_results`,
 * /installation/repositories also has `repository_selection`), as well as a key with
 * the list of the items which name varies from endpoint to endpoint.
 *
 * Octokit normalizes these responses so that paginated results are always returned following
 * the same structure. One challenge is that if the list response has only one page, no Link
 * header is provided, so this header alone is not sufficient to check wether a response is
 * paginated or not.
 *
 * We check if a "total_count" key is present in the response data, but also make sure that
 * a "url" property is not, as the "Get the combined status for a specific ref" endpoint would
 * otherwise match: https://developer.github.com/v3/repos/statuses/#get-the-combined-status-for-a-specific-ref
