Change membership level access does not send an email

[michaelbeil]

Describe the bug
With MMPU active, when you change the membership level of a member, an email is not sent out. A member saw this as reported in ticket 344696 (moderators only).

To Reproduce
Steps to reproduce the behavior:

1. Enable MMPU.
2. Find a test user, and change their Paid Membership access level to anything.
3. No admin email or user email is sent based on this new access when MMPU is activated.
4. Disable MMPU and emails will send again.

Expected behavior
I expected the emails to be sent out.

Isolating the problem:

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

WordPress Environment

``` Paid Memberships Pro 2.5.10, MMPU 0.8, Twenty Twenty-One 1.2, WP 5.7.2, and PHP 7.4.1 ```

A member reported this in ticket 359121 (moderators only).

When using the Multiple Memberships Per User Plugin, and changing a user’s membership level or adding a membership from User Admin panel, notification emails are not being sent to the user. Test emails however from the Member email settings however, do seem to be working.

I think this gets disabled as the function needs to support MMPU, which it currently doesn't do.
