Zaak 'heeft.indicatieLaatsteStatus' incorrectly uses zgw 'statustype.isEindstatus' instead of the current status of the zaak

[MLenterman]

Currently we follow zgw 'statustype.isEindstatus', which indicates if that statustype is the the last one that can be set on a zaak or not. However 'heeft.indicatieLaatsteStatus' should be indicating which of the set statusses on the zaak is the last one set, or in other words, the current status of the zaak.

This is relevant mostly for 'geefLijstZaakdocumenten' and 'geefZaakDetails'.
