[FIX] website_event: stop displaying messages on event page
[FIX] website_event: stop displaying messages on event page

A recent refactoring of mail.message induced a crash when redering the
front side of an event with messages/notes in its chatter. As there is
no use to such a feature, we simply remove the part that displays those
messages.
