Update autoscroll test to lift at the end and be less flakey

https://bugs.webkit.org/show_bug.cgi?id=197084

Test not lifting at the end caused issues for other tests.
Also the positions were a bit too exact and caused the
test to be flakey. These new positions should result in more consistent
behaviour.
