"The 'ZZ' address format can't be deleted." causes problems during config sync

I confirm this problem; I see it when I do drush config-import. I have the need to export config and commit to VCS so that collaborators can import it, and if the file address.address_format.ZZ.yml is in the imported config, I get this error:

exception 'Drupal\Core\Entity\EntityStorageException' with message 'The 'ZZ' address format can't be deleted.' in modules/contrib/address/src/AddressFormatStorage.php:19

My solution is to gitignore address.*ZZ.yml in my config directory

class AddressFormatStorage extends ConfigEntityStorage {

  /**
   * {@inheritdoc}
   */
  protected function doDelete($entities) {
    // ZZ is the fallback address format and it must always be present.
    if (array_key_exists('ZZ', $entities) && current($entities)->isUninstalling() === FALSE) {
      throw new EntityStorageException("The 'ZZ' address format can't be deleted.");
    }

So we either need to replace the isUninstalling() check with isSyncing(), or have both. Needs research.

The attached patch let's me import the config on site-install.

Ran into this, as well. Fixing issue status.

I believe this happens when you reset the site's UUID, so it will delete the format ZZ since the site's UUID does not match, but a new one will import.

Yep! This does the trick :D

Improved the fix and committed.
