Enhancement - Compatibility with BuddyPress (BuddyBoss) Registration.

[kimwhite]

Describe the bug When using the BuddyPress/Boss registrations form, Custom Roles are not assigned when using a snippet to add a default role .

To Reproduce Steps to reproduce the behavior:

1. Website with BuddyPress/Boss
2. Set up site to use BuddyPress registration.
3. Set up the level to assign multiple roles
4. Add snippet to assign default PMPro Level at registration
5. Go through Registration Process
6. Only the default role is added to users profile.

Screenshots

Expected behavior Member should be assigned all roles for that level.

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

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

WordPress Environment

``` WordPress 5.9.3 PMPro 2.8 Roles Add On 1.4.1 ```

Looking into this, the issue seems solely related to BuddyBoss/BuddyPress.

Tested with the default WordPress user registration and it works as intended.
