MDEV-27766: connect engine; INSERT ignore option, was ignored

Test prior to this change:

CURRENT_TEST: connect.mysql
mysqltest: At line 485: query 'INSERT IGNORE INTO t3 VALUES (5),(10),(30)' failed: ER_GET_ERRMSG (1296): Got error 122 '(1062) Duplicate entry '10' for key 'PRIMARY' [INSERT INTO `t1` (`a`) VALUES (10)]' from CONNECT

So the ignore table option wasn't getting passed to the remove server.
Closes #2008
