Names used to be fixed at creation and served by the relay for ever, so
no client ever needed this. The relay has now dropped them — and that
makes every group created before the change read as the placeholder on
every phone, with nobody left to ask what it used to be called. The relay
deleted its copy and no client had ever kept one.
Without a rename, those groups are called "Group" permanently. This is
the repair, and it is the first time a group's name has been changeable
at all.
Stored first, announced second: the name is ours the moment we set it, so
a member who cannot be reached now does not stop us seeing the group
under the name we chose. They pick it up from the next message, which
carries it.
