fix search items busting when current page+discussion

Wow, this is proving trickier than I thought it would.  Here's what I've got:

• If I warn the card_list as it is rendered, everything is fine
• If I warn the sidebar as it is rendered, the results are wrong
• If I warn the slot render of the search card, I actually seem to be seeing two different renderings - one correct, one wrong.

This is making me dizzy.

problem in get_slot() returning existing top level slot instead of new one.

Unclear what to test for - what doesn't (or didn't) work when clicking on the things offered in +example?

on Wagn.org, if you click on any item in Wagn news, that item's name changes to "Blog Entries By Date". This is still happening. Is Wagn.org not yet updated?
