Wind charges, wither skulls and fireballs cause entities to be launched extremely high when directly hit by them

This behavior was not mentioned in the changelog, but it exists since this snapshot. Note that this also affects heavy mobs like ravagers that should be very resistant to knockback in the same fashion. This bug makes it also easy to kill almost any mob by bombarding it with wind charges.

Steps to reproduce:

1. Summon any mob.
2. Throw a wind charge at it.
3. It flies up into the air.
