events: try nostrdb cache if we don't have one in-memory

Our nip10 logic looks for notes only in the in-memory cache. This means
sometimes threads don't get fully loaded if for whatever reason it's in
the nostrdb cache but not in-memory.

Ideally we would just remove our in-memory cache, but for now let's just
hack it so it falls back to nostrdb and makes an owned note.

Changelog-Fixed: Fixed threads not loading sometimes
