test(hub): join from an invitation link and land under the group's handle

The invitation probe listed no groups, so after Join the address stayed the
#/group/<id> the button navigated to and the group links' rewrite to
#/name@owner was never exercised on that path. A third case has the hub list
the group once joined, as it does: the group page opens, the address shows
the handle without a history entry of its own, and the code still never
reaches the hub.
