Correct an earlier pick

Amends commit 52909797ac, whose conflict
resolutions inadvertently incorporated the movement of IANA IDs from
the list table to the IANA table, a change only done on dev (6.9), not
picked back to 6.8, but tagged with a # TODO comment in 6.8 that, none
the less, is not to be done in 6.8.

Restore writing to the correct table.
