Last review should be a comment. When fetching the last message on a course
the returned message can be a system notification (like "Channel created").
This is not what we want, mostly with the feature allowing to modify the body
of a message. This commit add restriction on the domain fetch last message.
Fix default rating value on popup widget. The conversation ratio (rating 1-10
and 5 stars) was not applied everywhere. So, the number of displayed stars was
doubled. This is now fixed.
