Pagination not working for Comments API

[muhammadadeeltajamul]

Pagination is not working for comments API with Forum. Pagination work with same parameters when using cs_comments_service

Url I tested on : api/discussion/v1/comments/?thread_id={thread_id}&page_size=10&page=1&reverse_order=true&requested_fields=profile_image&enable_in_context_sidebar=false

@muhammadadeeltajamul: In general, when you're filing these bugs, can you please specify whether you're running the forums against MongoDB or MySQL?

[Ali-Salman29]

@ormsbee I've fixed the pagination issue in this PR. I've to add some tests only.

[muhammadadeeltajamul]

@ormsbee I will keep that in my mind when creating issues. All the issues I have opened till now, they are all on MongoDB.
