    wayland: Fix label lookup on >1 strips/rings
    
    We assumed that each group could only have 1 strip and/or ring, because
    accounting is performed per group, so we could not assume the real
    index for anything above 1. Get rid of this restriction, now that
    MetaWaylandTabletPad does its own accounting of rings/strips, alongside
    groups.
