On reacting to a message, raven will first update the cache optimistically, then wait for the response from the server and if the response is Ok, it will update the message in the cache. If the response is an error, it will rollback.
Post this, when the websocket event comes in for the reaction, the message will be updated anyway, so if there are multiple people reacting, it will reflect the correct value
