Fix and enable 'qp_functions_in_subquery_column' test.

When this test was ported over from TINC in commit 64f83aa8, I
accidentally left it out of 'greenplum_schedule'. Oops. It has somewhat
bitrotted since, due to changes in the error context messages. Fix the
bitrot, and enable the test in the schedule.
