Can't update shorten because of reference to Drupal 7.x updates in .install

Are the updates even needed?

Failed: Can not clear shorten_generate_token key in immutable configuration [error]
shorten.settings. Use \Drupal\Core\Config\ConfigFactoryInterface::getEditable() to
retrieve a mutable configuration object
