EntityKnockbackByEntityEvent is called twice if triggered by a player doing a strong knockback attack.

[r6653116]

Expected behavior

EntityKnockbackByEntityEvent would be called a single time every time an entity was hit.

Observed/Actual behavior

EntityKnockbackByEntityEvent is called twice if it is triggered by a player who does a sprinting attack.

Steps/models to reproduce

Create a Paper plugin, register an EntityKnockbackByEntity listener and broadcast a debug message every time it runs.

Punch an entity like a mob or an animal without sprinting. It should broadcast the debug message once.

Now punch the entity again while sprinting. It'll now broadcast the debug message twice.
