Fix valid function for the first call

[alkana]

commit 5c9bf86,

Problem : the function valid respond false the first time when the fetchAll must be done.

Solution : set directly rows field after the fetch.

Example to reproduce :
#1 Create table

CREATE TABLE IF NOT EXISTS user (
user_id int(10) unsigned NOT NULL AUTO_INCREMENT,
email varchar(70) CHARACTER SET utf8 NOT NULL,
password char(32) CHARACTER SET utf8 NOT NULL,
PRIMARY KEY (user_id),
UNIQUE KEY email_password (email,password)
) ENGINE=InnoDB DEFAULT CHARSET=latin1 AUTO_INCREMENT=3 ;

INSERT INTO user (user_id, email, password) VALUES
(1, '[email protected]', 'pass1'),
(2, '[email protected]', 'pass2');
#2 (use scaffold of phalcon-devtool)

phalcon scaffold --table-name user
#3 Search all result (juste enter in http://127.0.0.1/user/index page

or check like this :
$users = User::find();
while ($users->valid() !== false) {
echo "user : " . $users->current()->email . '
';
}

commit 8af3f1e,

Fix resultSet->seek function. replace range by while loop because range(0, 0) do one loop and apply next function.
