Register issue 867's replays: a delivery group's members checked beside each other (issue 867, ADR 0382)

R867, R-issue867-recheck, R-issue867-recheck-verb and R-issue867-release-group name mesh-controller's replay867_test.go at the merges of #348, #350, #351 and #352; prove shows each failing before its fix and passing on it.
