How to reproduce
* Open an article and edit one of the tracked fields
(title, root_article_id, parent_id).
* Open another article
* Re-open the first article
* Open the chatter
Current behavior
The chatter does not appear.
Expected behavior
The chatter should appear.
Fix
Instead of loading the chatter with the form view, load the chatter when the
user clicks on the chatter button.
Implements the use of the chatter component differently from the
form_renderer in mail, to be able to update/render it independently from
the rest of the view.
Hide the chatter button if there is no article in the form view since there is
no chatter to display in this case.
