Add product to website will reset has_options and required_options

[JeroenVanLeusden]

Preconditions

1. Magento v2.1.7
2. PHP v7.0.14
3. MySQL v5.7.16

Steps to reproduce

1. Create a 2nd website.
2. Create a configurable product with any attribute.
3. Add a Customizable Option (http://cloud.h-o.nl/krY0)
4. Save the product.
5. Open the tab Product in Websites and add you configurable to your created website.
6. Save the product.

Expected result

1. Entry in table catalog_product_entity should have has_options and required_options set to 1.

Actual result

1. The columns has_options and required_options are set to 0.
2. If you save the product again in the backend it will set has_options and required_options to 1 again.
3. After you added the product to you newly created website both columns are set to 0. If you add the product to your cart it will do so without your selected custom option.

Possible related

1. Product->save() shouldn't be called directly #8498 (applying this fix won't help).
