The first user to ever connect sends messages in double
Whenever the first user to ever connect a newly started Chut system in a new Erlang VM and does so via the web server, this user and this user only will send messages in double. Any client to connect to this user afterwards will behave the same, may it be via the web server or not. However, if the user timeouts and then a new client starts a new one with the same name, the problem is gone. The problem is also gone if the application is stopped and start again.
Effectively, this only happens on the first web connection of the first chut startup of a new VM.
