[v0.4] QueryOperator requires all given Components to have at least 1 occurrence

[pimdewit]

const entities = query(world, [Or(Mesh, InstancedMesh, Group)]);

It seems that on 0.4 the above query only works if the world has at least 1 occurrence of every Component listed in the world.

e.g. if there is no entity with the Group component in the world, it always returns an empty arr, even if Mesh or InstancedMesh are present.
