    Handle an UNKNOWN NetworkManager connectivity as NONE
    
    nm_conn_to_g_conn already handles UNKNOWN like NONE (returning
    G_NETWORK_CONNECTIVITY_LOCAL in both cases). So in sync_properties
    we should also set new_connectivity to G_NETWORK_CONNECTIVITY_LOCAL
    for both NM_CONNECTIVITY_UNKNOWN and NM_CONNECTIVITY_NONE.
    
    This has the added benefit that when NetworkManager returns the network
    connectivity is UNKNOWN, we set network_available to FALSE as it should
    be. Previously, there were cases in a laptop with no network access,
    that g_network_monitor_get_network_available returned true, which was
    wrong and is also fixed with this commit.
