One-to-many relationships are serialized with None value when eager-loaded

[federicoparroni]

Describe the bug
When one-to-many relationships is eager-loaded (using the _with function) from a record, the serialized value for the related field is set as None.

To Reproduce

class Category(Model):
    __hidden__ = [
        'id',
        'created_at',
        'updated_at'
    ]

    @belongs_to('website_id', 'id')
    def websites(self):
        return Website

class Website(Model, SoftDeletesMixin):
    __appends__ = [
        'categories',
    ]

    @has_many('id', 'website_id')
    def categories(self):
       return Category

data = Website.with_('categories').first().serialize()
print(data)    # data["categories"] is None

Expected behavior
The serialized value for the related field should be set as an empty array.

Also take out the appends. That’s for custom attributes. You have the with() already
