rails--rails/actioncable/lib/action_cable/server/configuration.rb
Kasper Timm Hansen 861ece99bb Default connection class to ActionCable::Connection::Base.
Instead of depending on ApplicationCable::Connection being defined at initialize
we should inject it in the Railtie.

Thus we can kill more setup in the tests too.
