Corrects "ext2spice hierarchy off" when subcircuits with ports are

present.  Note, however, this fix breaks the use of "ext2spice
subcircuit descend off" because subcircuits are always descended
into.  It's not clear that "subcircuit descend off" worked at all
before, anyway.  That still needs fixing.
