Cannot query versions in a folder with dbs pageprovider

ecm:parentId is not populated in mongodb for versions. However it is in the Elasticsearch index.

The following query returns nothing with a core pageprovider while it returns all the versions present in the folder with ES.

SELECT * FROM Document WHERE ecm:parentId = 'the folder ID' AND ecm:isVersion = 1

It feels like an exact match query on system properties should return the same results with both types of pp (assuming the ES index is up-to-date).

The current behavior of the ES pageprovider provides more query possibilities on versions than the core pp
