Fix factory function call to compability with Laravel 7

[marvin255]

My test for laravel 7 project:

$collection = $I->haveMultiple(Player::class, 3);
$playerToFind = $collection->random();

produces an error:

1) PlayerRepositoryCachedCest: Try find by primary
Test  tests/functional/Components/PlayerRepositoryCachedCest.php:tryFindByPrimary
[BadMethodCallException] Call to undefined method App\Components\Player::random()  

Call of factory function with 3 arguments is not supported now: https://github.com/laravel/framework/blob/7.x/src/Illuminate/Foundation/helpers.php#L486
