<rdar://problem/4495316> REGRESSION (420+): After page has loaded, spinning progress indicator is displayed on
        tab at versiontracker.com

        * WebView/WebFrame.m:
        (-[WebFrame _receivedMainResourceError:]):
        Call -_clientRedirectCancelledOrFinished: here so that the frame load delegate is notified that the redirect's
        status has changed, if there was a redirect.  The frame load delegate may have saved some state about
        the redirect in its -webView:willPerformClientRedirectToURL:delay:fireDate:forFrame:.  Since we are definitely
        not going to use this provisional resource, as it was cancelled, notify the frame load delegate that the redirect
        has ended.
        The fix for 4432562 was similar to this, but only took care of the case where the redirect load was actually
        committed to the frame.  The new call to -_clientRedirectCancelledOrFinished: handles the case where the redirect
        load was successful, but was not committed.  This happens with downloads.
