Subject: [PATCH] [linear][parallelhelper] remove obsolete mpi guard

On minimal setups without MPI installed, the box tests failed to compile
as the FVAssembler uses the ParallelVectorHelper class, which itself was
hidden behind a HAVE_MPI guard. Tests with setups where MPI is not
installed showed that the tests compile and run also without the guard.
