refs #3460219 Implemented missing method.
Fixes issue:
Fatal error: Class Drupal\config_track\Extension\ModuleHandler contains 1 abstract method and must therefore be declared abstract or implement the remaining methods (Drupal\Core\DestructableInterface::destruct) in /app/drupal/modules/contrib/config_track/src/Extension/ModuleHandler.php on line 15
Closes #3460219
