Maces incorrectly cause damage to the player

Maces will incorrectly cause damage to the player when jumping after hitting an entity with them from ~4 blocks away from the ground.

Steps to reproduce:

1. Build a pillar
2. Spawn a mob next to it
3. Jump off from the pillar and hit the mob about 4 blocks away from the ground
4. Keep jumping once you hit the ground

Observed result:
You take damage every jump you do 3-4 times

Expected result:
You don't take damage while jumping after landing.
