Fixed a bug introduced by the recent big merge

Somehow a line got deleted from ViewManager::make_subgroup_maps that
initialized curr_view.my_subgroups, even though the equivalent line in
ViewManager::derive_subgroup_settings was left in. This obviously broke
View changes since the new view's my_subgroups member never got
initialized.
