Customer facing prices compatibility with WooCommerce Subscriptions

[jessepearson]

We are aiming to have Subs support for the MVP. The issues in this epic are what have been found so far that need to be fixed to be compatible.

Things that still need to be tested:

• Coupons (all types)
• Resubscriptions
• Coupons with early renewals
• Coupons with switches
• Coupons with resubs
