[Auth-UI] [10.0.0-beta01] Unable to disable MFA; Can't log in with facbook account with no email

[khanshoaib3]

1. I tried disabling multi factor authentication with isMfaEnabled = false in the authConfiguration but it still navigated to the MfaEnrollmentScreen when signing with Google.
2. When trying to login with a fb account with no email, the login is unsuccessful, the error dialog appears with NetworkException.
   There is no error log but the following debug:
   FirebaseAuthUI.signInWithFacebook com.example.app D Profile fetched: name=Shoaib, email=, hasPhoto=true
