PDO fetch style FETCH_CLASS is expected to be used along a class name.

It currently works in Laravel because the latter does the following, which happens to work only by chance:

$results = $stmt->fetchAll(PDO::FETCH_CLASS);

However, the following would produce an error:

$stmt->setFetchMode(PDO::FETCH_CLASS);
$results = $stmt->fetchAll();

PDOStatement::setFetchMode(): SQLSTATE[HY000]: General error: fetch mode requires the classname argument

This PR switches to the proper fetch style, which is robuster, and even more importantly, less confusing for the user. It's fully backward compatible.
