in 3d our solutions are wrong. at least for poisson

check linear advection in 3d to check if problem is deep or just affects laplacian

it's pretty surprising that this bug persists, even though we rewrote pretty much the whole implementation by making it coordinate-free... Maybe something is wrong with the hyperbox mesh? We could check by using a different mesh e.g. gmsh or delaunay.
