On initial startup wdqs-updater is currently only waiting for any response on the host/port of mediawiki.
This leads to Mediawiki/Wikibase still being in the installation phase when wdqs-updater starts polling. There is nothing dangerous in this in itself but looks bad and spams the log (which may look like an error for users)
