Follow requests nobody answers are sent again

A Follow was resent only when the persona followed again. Lemmy 1.0
sends nothing it queued for a server before it started sending there, so
the Accept of a community follow made on first contact was lost for good:
the village's persona stayed "requested" a day while Lemmy listed her as a
follower, and every post the community announced was refused as not
followed. A request still unanswered is now sent again, the same activity,
after 15 minutes, an hour, 6 hours, a day, two and four days
(FollowResender, every 15 minutes); a server that holds the follow answers
the copy.
