Show 4 latest posts when site.related_posts is nil

`site.related_posts` should return an array of latest posts when no related ones are found due to `lsi` being disabled (GitHub Page's doesn't support it). This works around that bug by showing the 4 latest posts to populate the "You May Also Enjoy" module when enabled with `related: true`. Fixes mmistakes#554 Related: mmistakes#978 mmistakes#1022
