Description:
------------
When using PDOStatement::setFetchMode() with PDO::FETCH_CLASS and PDO::FETCH_PROPS_LATE a call without arguments to PDOStatement::fetch() wont work.

Reproduce code:
---------------
<?php
class Person
{
    public $parameter;
    public function __construct($parameter)
    {
        $this->parameter = $parameter;
    }
}

$db = new PDO("sqlite::memory:");
$db->setAttribute(PDO::ATTR_ERRMODE, PDO::ERRMODE_EXCEPTION);
$db->exec("CREATE TABLE person (id INTEGER NOT NULL, name varchar(100))");
$db->exec("INSERT INTO person(id, name) VALUES (1, 'Sven')");

$stmt = $db->query('SELECT * FROM person');
$stmt->setFetchMode(PDO::FETCH_CLASS | PDO::FETCH_PROPS_LATE, 'Person', array(0 => 'Parameter'));
/* To get the expected result you must use: $stmt->fetch(PDO::FETCH_CLASS | PDO::FETCH_PROPS_LATE);
Should that really be needed? */
$obj = $stmt->fetch();
print_r($obj);

Expected result:
----------------
Person Object ( [parameter] => Parameter [id] => 1 [name] => Sven )

Actual result:
--------------
$obj is false

If PDO::FETCH_PROPS_LATE is not used in PDOStatement::setFetchMode and PDOStatement::fetch() is called without arguments you get the expected result.
