Remove confirmation message about restoring query editor on restarted CM/CQB, Removed that it open a blank query edtior after close the cubrid notice window on specification

It is always asked a question "Do you want to restore a query editors." if you close CM/CQB having query editors with sqls.
But, it is so inconvience things.
And also, now, it can't assure exactly because of crashed or normal closed.
So, we decided if you closed it having opened query editors, it will be automatically restore without confirmation message because of safty for edited sqls.
