Subject: [PATCH] tests: prove a stable publish leaves a newer-family edge
 alone

A stable 3.3.x release routes to stable, testing and edge. When edge
already serves a newer family (4.0.0.a1), the publisher must update
stable and testing only and leave the edge catalogue byte-identical,
dependency included. The existing coverage exercised this with a
testing-primary release only.
