Title: Feature/FeatureCollection with ID=0 fails to add in GeoStore. JSON.stringify() on Terraformer Feature Primitive drops id field.

GeoStore would fail to add feature or featurecollection with id=0.

It also affected JSON.stringify() of a Terraformer Feature, which would just strip out the id attribute when id=0.
