setData called twice without redraw causes wrong point update

[KacperMadej]

Expected behaviour

Redraw argument of series.setData() used only for visual change.

Actual behaviour

After point is removed, series array of points contains "empty" point and causes setData to run point update by default in some cases.

Live demo with steps to reproduce

Single point is present, then removed (without redraw) and a new point is added (using setData, with later called chart.redraw).

Steps: press "remove" and after that "add"

Workaround

Call second setData with updatePoints argument set to false - https://jsfiddle.net/BlackLabel/3cw2dteh/1/
