Enable conversion from QJSValues containing arrays to container types

We started to convert containers to QJSValues, so that we could use them
as JavaScript arrays. Unfortunately, this would then lead to a type missmatch
when those same values where to be stored in a property of the container
type. This commit fixes this by converting them back to the original
type.

Fixes: QTBUG-80916
