Error: "undefined method `config' for MiaAuth:Module" when deploy to Heroku.

Bug report

The OmniauthCallbacksController invoke the invalid method when its try to loop call Omniauth provider.

# This will raise the error: undefined method `config' for MiaAuth:Module
MiaAuth.config.omniauth_providers.each do |provider|
    define_method provider do
        authenticate
    end
end

# Fix this issue by changing the `config` to `configuration`
MiaAuth.configuration.omniauth_providers.each do |provider|
    define_method provider do
        authenticate
    end
end

The configuration method has been defined in lib/mia_auth.rb
