Delay requesting game on join

[zchr]

There is a delay when landing on the game page (or the emit is not firing at all). My theory is that the client requests the game state before the server has added it to a room. Switch to using callbacks if possible.

This only happens sometimes, and there is also a disconnect issue. My guess is it's this has something to do with it: https://devcenter.heroku.com/articles/node-websockets

I think this was fixed by running heroku features:enable http-session-affinity (per the linked instructions). Will find out in due time.
