Outch! Now I really feel ashamed :((((

The good thing is that ApartFF always checks the final result,
so it can detect such issues by itself.

Anyhow, is now fixed:

<https://github.com/FeynCalc/feyncalc/commit/5b98e326b7a14140f6d42765a1d6da566b1c9494>

Please reinstall the stable version again and let me know if you find
more issues.

Cheers,
Vladyslav
