tests: update testcase for #314

Browse Source 
Handle more (hopefully all) edge-cases when updating `opacity_target_old`:
* `MAPPING` transitions to `FADING` if new target is reached. Otherwise
no update.
* `FADING` clamps to current `opacity` if old target is too small.
* `UNMAPPING`/`DESTROYING` clamps to current `opacity` if old target is
too small.
