Robin Lee 6795a2aeaf Check legacy VPN is connected before alerting
Legacy VPN does nothing if the device has no underlying network
connection, so showing this warning in that case is confusing.

Conversely third-party VPN can still be dangerous since a malicious
app will store sensitive information and upload it later.
