Fixing problem with scrolling and small list.

[daliusd]

There is following problem:

• Load big list

• Scroll to bottom

• Load small list

Result:

Content is not visible because scrollbar is outside of it.\

I have tried running tests with and without fix but they fail on my machine.

Most probably this is not really good fix but at least list always shows something.

I think that would be better to keep the view on the last item. (pseudocode)

viewport.scrollTo(currentX, content_height - listHeight);
