Upload WebRTC event logs over "unknown" connections

Previously, we were uploading only when CONNECTION_ETHERNET or
CONNECTION_WIFI were reported. However, it turns out that sometimes,
Wi-Fi connections are reported as CONNECTION_UNKNOWN.
We will therefore start uploading over any connection
other than NONE, 2G, 3G and 4G.
