ArgumentError when using activerecord models when defining a Washout::Type

when you define a washout type that contains also a activerecord model it fails with  ArgumentError  and messsage:
wrong number of arguments (1 for 0)


The issue was in Washout::Param class , the method basic_type

    def basic_type
      return name unless classified?
      return source_class.wash_out_param_name(@soap_config)
    end

But in Washout::Model the method  wash_out_param_name doesn't need any arguments

So i removed that argument when the function is called
