Remove avatar, name, timestamp and interactions from publisher preview

This doesn't add any value in the post preview:
* Avatar is already at the left-hand side of the publisher
* Timestamp is always "less than a minute ago"
* Interactions are disabled in the preview anyway

We don't display these things in the comment preview either, they only
need space and don't add any value to the preview.
