[restart] revert usage of BackupRestoreFacility

The BackupRestoreFacility does not work with ALUGrid 1.52. It also does
not work with dune-alugrid in combination with Dumux due to
technicalities that are documented in FS#237.

Therefore, the restart with adaptive grids currently does only work with
ALUGrid 1.52, not with dune-alugrid.
