BUG: Membership level is granted regardless of previously approved membership level requirement

[dwanjuki]

Describe the bug
When a membership level's Require Approval setting is set to Yes. User must have an approved membership for a different level, new users are able to check out for the level and get access to the content despite not having a previously approved membership.

To Reproduce
Steps to reproduce the behavior:

1. Create a membership level. Set it to require approval from an admin
2. Create a second membership level. Set it to require an approved membership from the first level.
3. Attempt to checkout for the second membership level, creating a new account.

Expected behavior
Checkout should be restricted as the new account does not have an approved membership for a different level. Instead, the membership level is granted.

Isolating the problem (mark completed items with an [x]):

• I have deactivated other plugins and confirmed this bug occurs when only Paid Memberships Pro plugin is active.
• This bug happens with a default WordPress theme active, or Memberlite.
• I can reproduce this bug consistently using the steps above.

I'm encountering exactly the same issue.
Don't know if this matters, but I was not able to find any records related to approvals in the database.
