Silently set 'version'=NULL if .git-repository does not exists

I use Composer template for Drupal project (https://github.com/drupal-composer/drupal-project) and there is no core .git repository in there. So on /admin/modules I have a lot of errors:

Notice: Undefined index: version in Drupal\system\Form\ModulesListForm->buildRow() (line 233 of core/modules/system/src/Form/ModulesListForm.php).
