I left that TODO in by accident after my clean up of the test case, I added the
case then. I've however also added one more case that you described above:
@Test
void shouldObserveNullWhenFlatMappedPropertyIsSetToNull() {
property.set("Right");
assertObserved("RIGHT");
property.set(null);
assertObserved((String)null);
}

Just trying to be thorough on testing all the `null` cases
