Seem to fix receiving messages 

Looking at runs where receiving messages work vs doesn't, in the case it
 does not work, js-chat is still receiving some messages as part
 of the identify process after subscribing.
 Whereas, when it works, the subscribe is done after those messages.
 With a 2s sleep to delay the subscribe, it seems that it always works.
