Issue with `insertMulti` and `setQueryOption("IGNORE")`

[ClemRz]

Assuming we try to do an insertMulti with one row of data which happens to be a duplicate of one in the DB.

echo("---" . PHP_EOL);
echo($mysqliDb->setQueryOption("IGNORE")->insertMulti($table, $data) . PHP_EOL);
echo("---" . PHP_EOL);

This returns:

---

---

Which happens to be falsy thus interpreted as an error during the insert attempt.
