Only call EntityDamageEvents before actuallyHurt (#11045)

Browse source 
The recent upstream update moved around the event logic for
EntiyDamageEvent and its derivatives.
However, the event was called on every call to #hurt as it was moved out
of actuallyHurt.

This patch moves the invocation directly before the #actuallyHurt calls,
respective invulnerable timings.
