Content gate should not appear on products with a membership discount and no restrictions defined

[mcmcghee]

Describe the bug
If a membership plan provides a purchasing discount for a product, the content gate displays despite there being no restrictions defined on the product.

To Reproduce
Steps to reproduce the behavior:

1. Have a product and a membership plan defined, with a purchasing discount defined on the plan for the product, and no restrictions defined on the product.
2. View the product on the front end, see the content gate is displayed on the product.
3. Uncheck the "active" box for the purchasing discount on the membership plan.
4. View the product on the front end, see the content gate no longer appears.
5. Make the purchasing discount active again.
6. View the product on the front end, see the content gate is displayed again.
7. Unpublish the content gate under Engagement->Advanced Settings.
8. View the product on the front end, see the product is not being restricted by Woocommerce.

Took another look at this and determined it is only an issue when using the inline gate. Switching to the overlay gate and it behaves correctly.
