fix(joining): bug where several peers join at once via the same peer.

Updates JSPM devDependecies. There where a bug when several peers join at once via the same peer.
This commit resolves this bug for 6 peers joining at once. Above this amount (Chrome behaves a
little bit better then Firefox) some errors due to setting remote answer may occure. I do not know
whether this is WebRTC issue or Netflux.
