Taking any damage before fatal fall damage removes the attacker credited for kill

The bug

Taking any damage before fatal fall damage removes the attacker credited for kill, affecting death messages and statistics.

Steps to Reproduce

1) Take damage from a husk
2) Take any environmental damage (fire, magma block)
3) Fall off a high place
4) "Player was doomed to fall"

1) Take damage from a husk
2) Take minor fall damage (e.g fall 4 blocks)
3) Fall off a high place
4) "Player fell from a high place"

If you had replaced Step 3 with any other way of dying (e.g /kill) it would have shown the attacker (Husk) in the death message.
