When an event is published/unpublished, the 'Is Published' value appears
twice in the chatter.
This is because `website_published` is defined as a related of
`is_published`, and `is_published` is tracked. The button calls
`website_publish_button` which triggers a `write` on
`website_published`, the latter triggering a `write` on `is_published`.
The situation is quite exceptional: we usually don't define a related on
a field of the same model. Therefore, we can simply change the field
tracked.
