Fix double click handler in QQuickItem.

The legacy, desktop-oriented way of calling mousePressed from the
default handlers for mouseDoubleClick is not working properly with
QWindow and QGuiApplication: In Qt 5 a double click will never
suppress any lower level events (like press or release) and therefore
simulating a mouse press in the double click handlers is wrong.
