[spaces.raciarthomas.pdelab] fix local_DoF_indices()
* there seems to be a bug in dune-commons FloatCmp, so instead of testing
  against 0 we add 1 on both sides
* the basis functions are extremely sensitive to local coordinate
  distortions, so we obtain the (entity) local vertex coordinates from the
  reference elements instead of the entities geometry's local()
