Trigger DidChangeVisisbleSSLState() after OverrideEntry()

While SSLBlockingPage::OverrideEntry() changes the visible SSL status of
the page, WebContentsImpl::DidChangeVisibleSSLState() never gets
called. This breaks the devtools security panel on interstitials and has
caused other bugs in the past (e.g. crbug.com/474795).
