Implemented: remove browsing context name on cross origin navigation

When updating the history after a cross-origin navigation, the HTML Standard says: "If the browsing context is a top-level browsing context, but not an auxiliary browsing context, then set the browsing context's name to the empty string." Currently we are not doing this which means there's potential information leak.
