When clearing the cache, we should pass user.GetMsalAccountId() because that is the cache key pattern that we are using. The previous code account.HomeAccountId.Identifier results in a bug for Guest accounts because Account Identifier has a different value than GetMsalAccountId(), resulting in not clearing the proper cache.
