Ensure player entity schedulers are ticked when they are dead

If the player dies, then they are removed from the world and
as a result are not present in the world entity map.

To guarantee that the player entity scheduler is ticked, we can
tick all schedulers for players in the server player list, and
then skip all players we find in the world entity map.

This problem is not present on Folia since Folia must guarantee
that the player remains in the world.
