Send the groups list Edit button to the group page, not the rename form

Every other list page with a detail view (Teams, Members, News, Events) has
Edit land on the overview; groups jumped straight to the rename form, skipping
the page where the members actually are. The group page already carries its own
Edit action, so nothing becomes unreachable.

The list pages that legitimately do go straight to a form -- Locations,
Opponents, Sponsors, Positions, Referee levels -- have no detail view at all,
which is why they stay as they are. Noted in the test so the inconsistency
doesn't read as one.
