Erik Johnston 5a7f561a9b Fix bug where pusherpool didn't start and broke some rooms
Since we didn't instansiate the PusherPool at start time it could fail
at run time, which it did for some users.

This may or may not fix things for those users, but it should happen at
start time and stop the server from starting.
