GetEntites throws a NullReferenceException if the world doesn't contain any entities that match the query

[MindSwipe]

Repro/ UnitTest for it:

[Test]
public void GetEntitesTest()
{
	world = World.Create();

	var archTypes = new Type[] { typeof(Transform) };
	var query = new QueryDescription { All = archTypes };

	var entity = world.Create(archTypes);

	var entites = new List<Entity>();
	world.GetEntities(query, entites);

	Assert.That(entites.Count, Is.EqualTo(1));

	entites.Clear();
	world.Destroy(entity);
	world.GetEntities(query, entites);

	Assert.That(entites.Count, Is.EqualTo(0));
}
