Source/WebCore: [Mac] Follow-up: After a horizontal overflow scroll with a mechanical wheel mouse, vertical scrolling no longer works
https://bugs.webkit.org/show_bug.cgi?id=131960
<rdar://problem/16142100>

Unreviewed build fix.

* page/EventHandler.cpp:
(WebCore::EventHandler::handleWheelEvent): The test to clear the
last scrolled node was too broad. It should only follow this path
if both the phase and momentum phase are 'None'.

Tools: Unreviewed build fix.

* DumpRenderTree/mac/EventSendingController.mm:
(-[EventSendingController mouseScrollByX:andY:withWheel:andMomentumPhases:]):
Correct a typo that prevented tests from working properly.
