Source/WebCore:

Fix a bug where WK2 didRemoveFrameFromHierarchy callbacks wouldn't fire for subframes that were getting
kicked out of PageCache. The problem was happening because CachedFrame would disconnect the Frame from
its Page just before calling FrameLoader::detachViewsAndDocumentLoader() where the callbacks are fired.
Without a Page, the WebFrame on WK2 side can't find its WebPage, and so it can't fire its callbacks.

The fix is just to switch the order of those two lines.

This bug was causing frequent DOM and window object leaks in some clients *cough* Safari *cough* that
were relying on didRemoveFrameFromHierarchy to release their isolated worlds.

Test: WebKit2.DidRemoveFrameFromHiearchyInPageCache

* history/CachedFrame.cpp:
(WebCore::CachedFrame::destroy):

Tools:

Add an API test that puts a 10-subframe page into the page cache, then loads other pages
until the first page gets kicked out. The test succeeds if we receive didRemoveFrameFromHierarchy
callbacks for all the subframes.

* TestWebKitAPI/Tests/WebKit2/DidRemoveFrameFromHiearchyInPageCache.cpp: Added.
