Follow-up: Changes are rolled-back by additional calls to `composer install`

I still have the problem described in #25. If I remove the modules/contrib directory and run `composer install` the version information gets added to the module.info.yml files calling `composer install` again will remove the the version information.

* drupal-composer/info-rewrite version 1.0.0-rc1 (composer.lock)
* Drupal Version: 8.9.1
* Composer version: 1.10.7.
