Ingo Schommer 8f5932acec Allow empty has_one returns in DataDifferencer
Sometimes the has_one getter is incorrectly implemented,
resulting in an empty return object. While that's technically
a core API validation, there's no checks around it (i.e. no PHP class interface).
DataDifferencer has the option to continue here, so we should
program it defensively rather than resulting in a fatal error.
