Sync dates for reg and sponsorship open form with list

In the list of open sponsorships we stopped listing sponsors once the
conference was started. But if one had saved away the URL for the signup
form it still worked. Make those two be in sync.

For registrations there were some places that would still list it and
others wouldn't, but the form would still work. So make the same fix
here, except trigger it on the *end* date of the conference so walk-up
registrations still work.
