Synapse sends presence EDUs whenever a user joins the room. However it currently sends them whenever it sees a m.room.member event with membership join, even if the user was already joined to the room. This causes problems because setting the displayname results in a new join event for each room the user is a member of, which in turn will cause synapse to send an EDU for each remote server joined to each of those rooms.
This PR should fix this by only notifying if the user wasn't already joined to the room.
