Post items do not sort correctly

[StevenJoynt]

Database columns updated_at and stream_sort_date are supplied by this module, but overridden by the Yii and humhub framework to be the current timestamp.
May need to run an additional query to frig these values after inserting or updating the post and content tables.

Ok now when sorting Posts by Last Update

Still random when sorting by Creation Time - This option probably shows items sorted by primary key (id) - i.e. the order items were inserted onto the database.

Now sorting RSS News Items by pubDate before inserting Posts in Space.
