[9.x] Factory fails to eval models and factories when returned from closure

[harrygulliford]

Since v9.12.0, due to the changes made in #42241, model factories now fail to evaluate both models and factories when they are returned from a closure.

This is due to models and factories now being resolved first and closures second.

To fix this issue, while maintaining the functionality added in #42241, the resolution of models and factories would need to be repeated again after resolving closures.

A rudimentary example:

class PostFactory extends Factory
{
    public function definition()
    {
        return [
            'title' => 'post',
            'user_id' => function (array $attributes) {
                return User::factory(['options' => $attributes['title'].'-options']);
            },
        ];
    }
}

In the latest release, the code above would throw an exception - occurring when the database driver attempts to bind a factory object the query statement (see failing test).

Error: Object of class \Database\Factories\PostFactory could not be converted to string
