Always call Elem* version of FE::shape()
Always call Elem* version of FE::shape()

For some FEs (e.g. BERNSTEIN) the Elem* version of FE::shape() is
required because edge and face orientation are needed to determine the
shape function values. Therefore, we always default to calling this
version when possible.
