BugFix: change key for geojson so it updates on change

[MartinRoberg]

Description

Using altinnrowid from datamodel instead of index+label as key for geojson-components to make sure the geometries update when changed. Added altinnrowid to geometry and rawgeometry type, and updated utils.ts for map to take altinnrowid into geometry from rawgeometry.
