Extra despawn with interest management = room

[cBournhonesque]

client 1 joins room A, entity x spawns and joins room A -> x leaves room A -> x despawns serverside -> server tells client 1 to despawn x despite x not being available to client 1

Normally the server shouldn't broadcast the A's despawn to client 1.

(i.e. there's a first despawn sent when x leaves room A, and then a second one when the entity is despawned)
