Call to a member function setSyncing() on null if Drupal view is removed and post_update hook is run

PR: https://github.com/civictheme/monorepo-drupal/pull/1322

Theme hook workaround to remove the config if it's invalid. So config is created but then removed:

use Drupal\Core\StringTranslation\TranslatableMarkup;

/**
 * Disable: Update alert api view to strip tags from visibility validation.
 *
 * Avoid error: "Error: Call to a member function setSyncing() on null"
 *
 * @see https://www.drupal.org/project/drupal/issues/3051453
 *
 * @SuppressWarnings(PHPMD.StaticAccess)
