Since [1], the `temporary_id` of a message is passed to the `message_post` route in order to renconciliate the temporary message on the client side and the real message created by the server. This led to crashes when sending message on the chatter because this parameter was not allowed as a `_notify_thread` parameter. Since this parameter is highly specific and isn't linked to any business/model code, this parameter is now passed via the context thus solving this issue.
