As shaped, two DROP ROLE queries included in "user_activity" were showing in the reports for "wal". The intention is to keep each test isolated and independent, so this is incorrect. This commit adds some calls to pg_stat_statements_reset() to clean up the statistics once each test finishes, so as there are no risks of overlap in the reports for individial scenarios. The addition in "user_activity" fixes the output of "wal". The new resets done in "level_tracking" and "utility" are added for consistency with the rest, though they do not affect the stats generated in the other tests. Oversight in d0028e3.
