Fix clustering-test app rpcs to add new data ensuring parents
The add-person rpc needs to pass true for ensureParents when adding
a person into the datastore. This ensures that it can be called on
an empty model.
Similarly when the CarBought notification is received and we try to
add a car-person to the datastore we need to do it with ensureParents
so that the data can be added to an empty model.
