[BUG] Phalcon\Mvc\Model\Row does not fully implement Phalcon\Mvc\Model\ResultsetInterface

[thewalkingtoast]

These work just fine:

// works
$user = User::find()->toArray();

echo json_encode($user);

// works
$user = User::findFirst()->toArray();

echo json_encode($user); 

However, adding conditions breaks Model::findFirst():

// works
$user = User::find([
     'columns'    => 'id,company_name,email',
     'conditions' => 'id = ?1',
     'bind'       => array(1 => '1')
])->toArray();

echo json_encode($user); 

// Fatal error: Call to undefined method
// Phalcon\Mvc\Model\Row::toArray()
$user = User::findFirst([
     'columns'    => 'id,company_name,email',
     'conditions' => 'id = ?1',
     'bind'       => array(1 => '1')
])->toArray();

echo json_encode($user);

My thought is that

echo json_encode(User::findFirst()->toArray()); // works
echo json_encode(User::findFirst($conditions_array)->toArray()); // doesn't work

feels inconsistent even though in the first example, the toArray() is unnecessary.

But did Phalcon\Mvc\Model\Row mean to implement Phalcon\Mvc\Model\ResultsetInterface?

As far as I can see, this class implements only two interfaces: ArrayAccess and Phalcon\Mvc\Model\ResultInterface, it does not have any necessary methods to implement ResultsetInterface.

@phalcon what do you think?
