Removed WebContentsImplTest::CrossSiteNavigationCanceled

This test checks that if a new navigation does not commit after the
current renderer has run its unload handler this does not leave the WebContents
in a stuck state. However, following
https://codereview.chromium.org/464593003/, the current renderer will only run
its unload handler after teh new navigation has committed. Therefore, this test
is no longer applicable.
