    network: Avoid JS error when activating VPN connection
    
    If the call to settings.get_connection_by_path in
    ensureActiveConnectionProps returns null, we'll hit a JS error here.
    Seems to happen always when activating a VPN connection. Avoid that.
    
    Giovanni says:
    
    "I believe this is papering over an existing bug, but it's possible for
    settings.get_connection_by_path() to legitimately return null (if the
    connection is owned by a different user and invisible to the current
    one), so the fix is correct anyway."
