remove implication pocky_kiss -> shared_food
Shared food is for when "two characters both have a single piece of food or candy in their mouths". But there are some cases where the characters are about to pocky kiss but aren't actually sharing the pocky yet. See post #2710152, post #3229421, post #2966149, and especially incoming pocky kiss.
See topic #6034 for the original discussion of this implication.
EDIT: The bulk update request #1853 (forum #152203) has been approved by @Hillside_Moose.
