Lukáš Tinkl 95f6350e8f feat: Passing an empty seq to dataChanged doesn't apply all roles
When calling `QAIM.dataChanged(index, index, [roles])`, passing nothing
(ie omitting the paramater altogether), an empty array `[]`, or an empty
sequence `@[]` means "all roles", just like the C++ counterpart in
https://doc.qt.io/qt-5/qabstractitemmodel.html#dataChanged
