These three events are just used to sync the model to reflect the changes. As nothing in gr-diff and descendents needs the comment model anymore, we can remove that property and instead do the updating in gr-diff-host, where we still need the comments model property to be kept in sync. This change removes the last dependency on the comment model from gr-diff and descendents, so they can now be reused indepedently of Gerrit's comment model.
