Remove checking head Repo when retrieving PR.

Seems that 'pull_request_review' headRepo is set wrongly in
case of PRs from forks. In 'pull_request' it points to headRepo
but in 'pull_request_review' it points to target repo

This PR should work in both cases by omitting checking the
head repo, only comparing branch and sha and adding pagination in
case the list will be long
