A restore without "shades" skipped the shade and group records but not
the room records, which come first, so it read the repeaters and the
settings from room data. The skip is now shadeModelBytes(), in a
ConfigHeader.h the native tests can reach, which counts rooms, shades
and groups. Found during LOOP_QUEUE_PLAN.md's review.
