Fix isHydrated() returning false with typed public properties

[enlivenapp]

I created a subclass with typed public properties:

class User extends \flight\ActiveRecord {
    public function __construct($pdo = null) {
        parent::__construct($pdo, 'users');
    }
    public int $id;
    public string $name;
}

After calling find() on an existing record:

$user = new User($pdo);
$user->eq('id', 1)->find();

I expected isHydrated() to return true, since the property values are populated correctly ($user->name returns "John").

Instead, isHydrated() returns false. This causes patterns like the following to always return null:

$user->eq('id', $id)->find();
return $user->isHydrated() ? $user : null;

Subclasses without typed properties are not affected.

Tests included. All existing tests continue to pass.

This fix might be at odds with your other PR that I just merged. Want to resolve the conflicts and let me know? Thanks!

It was indeed. Apologies for the messy PR business. in the attempt to keep things separate so it'd be easier for you to pick what you wanted to use I did too much separation. This is now a 33/34 combo merged together (since 33 needed 34 to work). rebased, etc etc...
