[gvfs] client: Use g_warning if proxy creation failed

[Ondrej Holy <oholy src gnome org>]

    client: Use g_warning if proxy creation failed
    
    Currently g_errprint is used and thus a message doesn't end up in a logs.
    Use g_warning to log the message and also replace g_return_if_fail,
    because proxy creation failure isn't programmer error.
