scrollingcoordinator/ios/ui-scrolling-tree.html is a Flaky Failure on iPad
https://bugs.webkit.org/show_bug.cgi?id=203119
rdar://problem/52970947

Reviewed by Wenson Hsieh.

iPad viewport heuristics (WebPage::immediatelyShrinkToFitContent()) run on a zero-delay
timer after page load, which races with this test getting the UI-side scrolling tree
and makes the test flakey.

Fix by turning off the heuristics with "contentMode=mobile". Also fix the test
to use UIHelper to get the scrolling tree.
