Error on 'null' paths for metapackages

[lazysoundsystem]

A recent change in composer - composer/composer#11455 - now breaks preserve-paths when it deals with metapackages.

Error: Composer\Util\Filesystem::isAbsolutePath(): Argument #1 ($path) must be of type string, null given, called in .../vendor/drupal-composer/preserve-paths/src/PluginWrapper.php on line 190

Reproduction case in #42 reproduces this every time.

Confirming that, as suggested in #44, sticking with composer version 2.5.5 avoids this issue until this package is updated.
