DERBY-3303: Fix OrderByColumn.java to account for "pulled" GROUP BY columns
when a) checking to see if the user has specified a valid ORDER BY column,
and b) trying to resolve "pulled" ORDER BY columns to their underlying values.
Also, add some relevant test cases to the existing lang/orderby.sql test.
