Second derivatives on nonaffine domains break in element table extraction

[Martin Sandve Alnæs]

Reproduce with:

from dolfin import *
parameters["form_compiler"]["representation"] = "uflacs"
mesh = UnitDiscMesh(mpi_comm_world(), 3, 2, 2)
V = FunctionSpace(mesh, FiniteElement("CG", mesh.ufl_cell(), 2))
f = Function(V)
print assemble(div(grad(f))*dx)

Initial incomplete attempts at fixing in

This might be fixed already but needs testing to say for sure.

This issues blocks removing the quadrature representation.
