A Regular added from a recipe link stores recipe_url, and its grounding job
grounds that link. Renaming the dinner while still pending kept the link, so
the job queued for the new name still attached the old link's recipe and
photo. UpdateDinner now sets recipe_url, and renaming a pending dinner
clears it: the fresh job grounds the new name by search, and the household
can give a link by hand to fix up the recipe if they want a specific one.
