QConcatenateTablesProxyModel does not react to rowsAboutToBeMoved/rowsMoved

When using a QConcatenateTablesProxyModel as the model of QML ListView, the list is not refreshed when we move an item of one of its source models

The attached example displays:

• a ListView, its model is a QConcatenateTablesProxyModel which uses two source models (2 QQStringListModel)
• two buttons. Each button triggers a moveRows call on one of the source model used by QConcatenateTablesProxyModel

When we press a button:

• the QQStringListModel is updated as expected. If we print the content of our QConcatenateTablesProxyModel we get the expected result
• the listview is not refreshed (items are not reordered)

QConcatenateTablesProxyModel does not subscribe to the rowsAboutToBeMoved and rowsMoved signals of its source models and does not propagate them. It therefore does not notify the QML ListView that it must reorder its items.
