Fix jump and property changes on first move when dragging a Flickable.
Fixes a regression whereby on the first mouse move the contentItem was
moved the total distance from the touch point to where the drag
distance was exceeded. For large drag thresholds this causes a
noticeable jump.
Task-number: QTBUG-30032
