For simplicial toric varieties, the rational cohomology ring and the
ratironal Chow group are isomorphic. So if all normalizations are correct,
then one should be able to do intersection computations in the cohomology
ring. This patch fixes the `volume_class()` and the constructor of
cohomology cycles from cones to make everything work.
