Always update the WebView's SSL certificate, regardless of whether a WebViewClient has been set

This looks like a copy-paste error from other CallbackProxy methods which call
back to the WebViewClient or WebChromeClient, rather than the WebView.

Also remove '@hide' annotations. These are superfluous as the class is not
public.
