  #
  # This is a fix to make spinach feature tests passing:
  # Controller actions are returned from AbstractController::Base and methods of parent classes are
  #   excluded in order to return only specific controller related methods.
  # That is ok for the app (no :create method in ancestors)
  #   but fails for tests because there is a :create method on FactoryGirl (one of the ancestors)
  #
  # see https://github.com/rails/rails/blob/v4.2.7/actionpack/lib/abstract_controller/base.rb#L78
