Comment 0 for bug 1374674

Situation goes as such :

- A view has been commented by another user :
     - the owner receives a notification --> Good
- the owner replies to the comment in his view
     - the owner gets a notification --> not required
     - the user who left a comment should be notified that a new comment has been made (bug/738882)

Part of the situation has already been reported (bug/738882)
but part of it has not.

The person who writes a comment on his own view should not be notified of a new comment.
