Fix ActiveRecord::Relation#cache_key for loaded empty collection
- Before this patch if we try to find cache_key of a loaded but empty collection it used to give error because of trying to call `updated_at` on `nil` value generated by `collection.max_by(&timestamp_column).public_send(timestamp_column)`. - This commit fixes above error by checking if size is greater than zero or not.
