Fix CI: rewrite tests to directly test _off_to_on_state_event_is_from_turn_on

The original test failed because HA light groups are expanded - the group
itself is removed from self.lights and replaced with member lights. This
means on_to_off_event is never stored for the group.

Rewrote tests to directly test _off_to_on_state_event_is_from_turn_on():
- test_off_to_on_state_event_is_from_turn_on_detects_group_members
- test_off_to_on_state_event_is_from_turn_on_respects_timing
- test_just_turned_off_polling_artifact_still_detected (negative case)
