Users cannot manage their active user upgrade if all user upgrades are disabled and no longer able to be purchased

[Jake B.]

Affected version

2.2.X

If you disable all user upgrades users can no longer access the user upgrade account page, which is normally expected. However, if a user has an active subscription this means they are no longer able to cancel or manage their active subscription.

Steps to reproduce:
1. Create a user upgrade
2. Purchase that user upgrade
3. Disable that user upgrade
4. Attempt to upgrade the user upgrades page as this user
