[PATCH v2 3/3] advapi32/tests: Clean up double NotifyServiceStatusChange() tests.

[Zebediah Figura]

Simplify different paths, explicitly test data2.was_called, and test
that the correct notification is produced for Windows 8+ (previously
an intermittent failure was observed due to this uninitialized field).
