Do not reload page after adding comments in Pull Request reviews (#13877)

Fixed #8861 
* use ajax on PR review page

* handle review comments

* extract duplicate code

FetchCodeCommentsByLine was initially more or less copied from fetchCodeCommentsByReview. Now they both use a common findCodeComments function instead

* use the Engine that was passed into the method
