Fix for SQL test src/test/BugTracker-2009 dumping_tables.SF-2776908--optimizers. Don't start a new result set if we've only had comments so far.  The test first sets the debugmask to OPTDEBUG which produces comments before the real result.  Mclient's get_schema didn't expect two result sets for a simple query, which caused the test to fail.
