redistribute Limit nodes nested in MinMaxAggPath

Make sure min/max path are redistributed. Doing it in createplan.c
is probably only a temporary solution, though. First, it breaks
the costing model (the path cost does not include the redistribution),
and it also probably breaks how distribution is propagated up the
path tree.
