Empty table alias in query, in Builder method addFrom()

[Jeckerson]

Found bug in Phalcon API (https://github.com/phalcon/phalcon-api/blob/master/library/Traits/QueryTrait.php#L89)

$builder = new Phalcon\Mvc\Model\Query\Builder();
$builder->addFrom(Users::class);

Which generates incorrect query

SELECT [].* FROM [Niden\Models\Users] AS [] WHERE ((username = :username:) AND (password = :password:)) AND (status = :status:)

It works correctly if specify second parameter of addForm() method.

$builder = new Phalcon\Mvc\Model\Query\Builder();
$builder->addFrom(Users::class, 'table1');
