fix(state): fix not being able to use any entity native calls in 'entityRemoved'

[AvarianKnight]

Goal of this PR

Fix oversight in 8957209 which added the IsEntityValid to makeEntityFunction, this is only needed for checks that an entity is valid (i.e. DOES_ENTITY_EXIST, and to a lesser extent, NETWORK_GET_ENTITY_FROM_NETWORK_ID) and pool getters.

How is this PR achieving the goal

Swap back to the old check for makeEntityFunction
