fix: Combine Group and GroupHistory when counting

[jennifer-richards]

Fixes #6683

[jennifer-richards]

I'm assuming here that a group's acronym is not going to change - if that's not true, then a different fix will be needed

[jennifer-richards]

Hmm. There are some exceptions - not sure if we need to worry about more.

>>> pp([(a, b, c.isoformat()) for a, b, c in list(GroupHistory.objects.exclude(group__acronym=F("acronym")).values_list("acronym", "group__acronym", "time").order_by("-time").distinct())])

Ok - this should handle changes to the group acronym now.
