D7078: [server] Fix crash when sending selection to a DDI without a DataSource

[David Edmundson]

  I don't think we did go in there because we have a selection, otherwise other->selection() wouldn't be null.
  
  If we want DDI::sendSelection(DDI *other) to always keep the client in sync we should do:
  
    auto selection = other->selection();
    if (!selection) {
        sendClearSelection();
        return;
    }
  
  the send_selection spec says we should be passing a null resource if we have no selection, whereas this version creates a data offer with nothing in it.
