Fix corner case causing TypeError in userJoin 

I believe this issue was caused by a single user in the channel being kicked for a duplicate login, thereby unloading the channel while the for loop was iterating, so this.users became undefined before the loop exited and thus there was a TypeError for reading this.users.length
