How detect HTTP RESPONSES different than 200 on paginated objects?

@richet 

Previously the SDK [was able to detect if a paginated query returned a non 200 response](https://github.com/onelogin/onelogin-ruby-sdk/blob/75d64bac747120088ae06974f78275db048e439b/lib/onelogin/api/client.rb#L423), but after the cursor refactor, we are not able to detect when API returns 400 or 401.
