Flickable: remove spurious emission of content size changes
If contentWidth or contentHeight is negative (unspecified), Flickable
should not emit contentWidthChanged() or contentHeightChanged() when
its own geometry changes. The value of contentWidth or contentHeight
does not change. It remains negative (unspecified).
