Refactor attribute_list_spec.rb to conform to Let's Not style (#1341)
* Refactor attribute_list_spec.rb to conform to Let's Not style * PR feedback * Re-name 'list' method to 'build_attribute_list', and extract to top-level scope so it can be re-used * Removed some unnecessary attribute declarations * Wrap 'build_attribute_list' method inside a module, so it's not defined on the global Object class
