Title: Missing datenstand for some layer

This PR addresses the issue described in https://github.com/geoadmin/mf-geoadmin3/issues/710

Some layer which are actualised very often, do not have a `datenstand` but only a key word `bgdi_created`. For these layer, we have to scan the source table for the latest date, which isused as a `datenstand`.
