    telepathyClient: Use :reachable for connectivity
    
    GNetworkManager:network-available uses a very generous definition of
    "available", which doesn't necessarily imply that we can actually
    establish a connection to any server.
    
    The new Account:reachable property is much more specific and thus
    provides a much more adequate state.
