    ephy-session: Save the pending API request URL if EphyWebView address is about:blank
    
    EphyWebView address is NULL (returned as about:blank) between the
    load_url() and the WEBKIT_LOAD_STARTED event, but WebKitWebView knows
    the pending API request URL. So use that to prevent losing the URL if
    the browser is closed before the WEBKIT_LOAD_STARTED event. This usually
    happens when the UI process crashes early, right after the session is
    loaded but before restored pages have started loading.
