Title: fix the collective communication object which is returned by CpGrid::comm()

If I'm not mistaken, then Dune expects that the template argument to
the collective communication is type of the communicator returned by
Dune::MPIHelper::getCommunication(). I used this as an argument to a
method of mine and CpGrid made the compiler bail out. This patch fixes
the issue.
