Summary
Fixes #416 —
valueStreamthrowsmissingDatawhen a string property is set to"", permanently killing the listener.The ObjC++ bridge in

test_value_withEmptyStringProperty_returnsEmptyString— one-shot value request returns""test_valueStream_withEmptyStringProperty_yieldsEmptyString— stream yields""without throwing
