Title:
  broken transform_data on refine

Status in DOLFIN:
  Fix Released

Bug description:
  I've realized that somewhere during last year refinement features has
  been broken. Not whole refinement, but only the part responsible for
  MeshData transformation between old and new mesh. This is code was
  written by me, so I'll try to fix it, but maybe some of you guys can
  take a quick look and help me which recent change could cause this
  problem.

  ===== Code to repeat crash =====
  #include<dolfin.h>
  using namespace dolfin;
  int main(){
   UnitCube mesh(10, 10, 10);
   mesh.data().create_mesh_function("material indicators", 3);
   MeshFunction<bool> mf(mesh, 3);
   mf = true;
   Mesh newmesh;
   newmesh = refine( mesh, mf);
  }

  ===== Error messages =====
  Refining simplicial mesh by recursive Rivara bisection.
  a.out: dolfin/mesh/MeshFunction.h:136: const T& dolfin::MeshFunction<T>::operator[](dolfin::uint) const [with T = unsigned int]: Assertion `index < _size' failed.
