Deleting OTP user deletes Auth0 profile, even if an AdminUser or ApiUser.

[binh-dam-ibigroup]

Observed behavior

Deleting an OtpUser that is also an ApiUser or AdminUser deletes the Auth0 profile, so that the remaining ApiUser and AdminUser associated with that profile can no longer log in.

Expected behavior

On deleting a user, the Auth0 profile should be deleted only if no other ApiUser/AdminUser/OtpUser is attached to it.

Steps to reproduce the problem

1. Create an Auth0 profile.
2. Create an AdminUser, an ApiUser, and an OtpUser with the same email.
3. Using the admin UI, delete the OtpUser.
4. Try login into the admin UI using the same email. Login will fail.
