Converting from elog 2.9.something to new elog 3.1.0 elogd refuses to start, instructs running elconv in one logbook.

When I do so, elconv converts a existing mhttpd-style elog entries to the new format (the corresponding new-format entries already exist)
and deletes everything else - this is very bad.

So there are 2 bugs:
- elogd should not tell us to run elconv when both old-style and corresponding new-style elog entries exist
- elconv should not delete all existing new-style elog entries.

I confirm that elconv *does* delete all new-style elog entries - with strace, I see it issue "unlink" on every elog entry.

What a disaster!
