  Fixed BUG#13616: "CALL <dbname>.<procedurename>" executes properly, but
                   displays error
      When returning to the old database (which may be ""), don't do
      access check - mysql_change_db() would then generate the error
      "No database selected".
      Note: No test case added; it seems a db is always selected when running
      tests.
