Memberships are not cancelled for unvalidated accounts on subscription cancellation

[dwanjuki]

Describe the bug
If a level requires email confirmation, if a member of the level hasn't confirmed their email, subscription cancellation at the gateway does not affect the associated membership. The membership continues indefinitely.

pmproec_pmpro_has_membership_level causes pmpro_hasMembershipLevel to return false here for members with unconfirmed emails even when they still have the membership level.

To Reproduce
Steps to reproduce the behavior:

1. Require email confirmation for a recurring membership level.
2. Check out for the level, do not confirm your email address.
3. Cancel the subscription at the gateway.
4. Observe that the membership remains unchanged.

Expected behavior
Membership is changed to cancel on next payment date.
