test: remove the NetworkObjectSpawning hybrid fixture

Its only hybrid case left running, CannotSpawnBeforeApproved, spawns nothing outside distributed
authority, so it passed without exercising hybrid spawning. The other two tests depend on in-scene
placed NetworkObjects and on InstantiateAndSpawn, which does not yet select the NetworkManager's
world for hybrid prefabs.
