CppunitTest_sw_tiledrendering2: make this more stable, try 3

I got the workaround condition wrong in commit
d248d8f527
(CppunitTest_sw_tiledrendering2: try to make this more stable,
2024-11-20), the intent was to return early when we get no state
changes, but we did the early return when there *were* state changes,
fix this.
