Dan Bode b6b13ce1b2 Handle case where ring_builder has no rows ...

The code was not robust when no
rows were returned from
  swift_ringbuilder(builder_file_path).

The calls to retrieve an array range from the
array of this commands output was returning nil
which caused the failure: undef method each on nil

This change explicitly checks for the case where
there are no rows returned by swift-ring-builder.
