Bad configuration if selecting devise invitable.

[modreoci]

If devise invitable gem is selected in custom app it does not properly set application controller for that gem. There is missing addition of this code:

before_filter :configure_permitted_parameters, if: :devise_controller?

protected

def configure_permitted_parameters
  # Only add some parameters
  devise_parameter_sanitizer.for(:accept_invitation).concat [:first_name, :last_name, :phone]
  # Override accepted parameters
  devise_parameter_sanitizer.for(:accept_invitation) do |u|
    u.permit(:first_name, :last_name, :phone, :password, :password_confirmation,
             :invitation_token)
  end
end

to the application_controller.rb according to README
