s/union/union all/

Using union without 'all' seemed to cause some incorrect results in
invoice_costs for reasons I can't entirely explain.  The CTEs 'costs'
and 'forecast' should *never* have any rows in common because the
month_type column can never be the same!  And yet I get different
results with union vs. union all.
