Fatal error when running "drush updb"

When running "drush updb" I got this error message:

LogicException: Render context is empty, because render() was called outside of a renderRoot() or renderPlain() call. Use         [error]
renderPlain()/renderRoot() or #lazy_builder/#pre_render instead. in

As the message suggested, I tried changing the ->render() calls to ->renderPlain() in xmlsitemap.install and after that everything worked fine again.

Attaching patch in comment.
