Reverted because the navigations in these browser tests were creating
WebHistoryItems, which depend on WebKit's Platform being initialized for
WTF::currentTime() to work.

Will take another crack with only #include removals, no code changes.  The rest
will have to wait for the WebHistoryItem cleanups.
