Exception raised if `profile` scope is excluded

[letmaik]

Describe the bug When the profile scope is excluded, then an exception is raised. I need to request only the "email" scope.

To Reproduce

app = msal.PublicClientApplication(
    APP_ID,
    # Historically MSAL hardcodes openid, profile, and offline_access scopes,
    # but we don't want all of that.
    exclude_scopes=["profile", "offline_access"]
    )
result = app.acquire_token_interactive(
    scopes=["email"],
    prompt='select_account',
)

Expected behavior No error should be raised.

Hi @letmaik, thanks for reporting this. Somehow, I am not able to reproduce this issue with our test app and test user. We may probably still change that line to a more robust implementation, but ideally we would also like to know why this issue was observed in your scenario.

Would you mind sharing your "client_id": "b218d3ca..." to me (via email), so that I can double check?

I just sent you an email.
