/**
* 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:
*
* - https://developer.github.com/v3/search/#example (key `items`)
* - https://developer.github.com/v3/checks/runs/#response-3 (key: `check_runs`)
* - https://developer.github.com/v3/checks/suites/#response-1 (key: `check_suites`)
* - https://developer.github.com/v3/apps/installations/#list-repositories (key: `repositories`)
* - https://developer.github.com/v3/apps/installations/#list-installations-for-a-user (key `installations`)
*
* 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. For the exceptions with the namespace, a fallback check for the route
* paths has to be added in order to normalize the response. We cannot check for the total_count
* property because it also exists in the response of Get the combined status for a specific ref.
