When an Insight doesn't implement HasDetail, we cannot see it's Class with -v option.

// example
• [Architecture] Property per class limit: (ObjectCalisthenics\Sniffs\Metrics\PropertyPerClassLimitSniff)
  src/Domain/Collector.php:13: "class" has too many properties: 40. Can be up to 10 properties.

• [Architecture] The name property in the `composer.json` contains the default value

This fix allow that
