Project is not updated when using "InsertTrackAtIndex()"

[Argitoth]

"Update" API broken when it comes to adding tracks. Python and EEL have same behavior.

does not update the scroll bar, cannot scroll (except with mousewheel) to lowest track unless I do something to force scroll bar update (add track via actions, do some kind of zoom action)

 // update functions are useless here.
loop(30,
	index = CountTracks();
	InsertTrackAtIndex(index, 0);
);

UpdateArrange();
UpdateTimeline();
TrackList_AdjustWindows(False); // <-- not useless actually

This is still present in v5.40. And there seems to be a bigger problem than this which can lead to deletion of items as I reported here:

Yeah, we can improve this.

For best compatibility with old versions, I suggest adding:

 Undo_OnStateChangeEx("whatever",-1,-1)
