    TCPStreamDialog: prevent access to uninitialized memory
    
    If we launch a TCPStreamDialog in a situation where we can't select a
    corresponding tcp stream, we leave the constructor before graph_
    is initialized.
    
    Later on, the destructor calls graph_segment_list_free(&graph_).
    This requires that graph_ was initialized before.
    
    Make sure that we initialize graph_ in the constructor, regardless
    of errors.
    
    (There's other aspects of this issue. We shouldn't be able to
    launch a TCPStreamDialog when we have no tcp stream...)
