mysqldump fix for invisible column

Browse Source 
Actually there are 2 issues in the case of invisible columns

  1st `select fields from t1` will have more fields then `select * from t1`.
So instead of `select * from t1` we are using `select a,b,invisible from t1`
these fields are supplied from `select fields from t1`.

  2nd We are using --complete-insert when we detect that this table is using
invisible columns.
