update references when renaming+discussion

this doesn't happen for all cards, but it does for that one.  not sure exactly why yet.  this is "medium" because it negatively impacts data.

I thought maybe Lew's changes would fix this, but it appears they didn't.

I got this behavior to happen with Renaming touching too many cards. Then I tried renaming it on dwagn, and it still broke.
