COLUMNS

Post-push fix: Fix test failures in
test_service_sql_api.test_session_general_log and
test_service_sql_api.test_sql_general_log.

When the missing tab character was added back, loading the
general query log with LOAD DATA INFILE produces an extra
column due to the tab being a separator character. Adjusted
tests to take this into account so that the test output
remains the same.
