[FIX] portal: dynamic chatter not editable

60c920d4a should solve duplication of chatter when editing the website.

But portal module doesn't depends on website, so eg. on a instance with
just helpdesk (and no website) we would not see the chatter on the
frontend.

This fix reverts 60c920d4a and adds another solution not depending on
website.
