fix slice alias crash after same document navigation

Browse Source 
The WPT tests navigation-api/navigation-methods/navigate-history-push-same-url.html
crashed with a @memcpy arguments alias error.

It seems to be due to the reuse of the previous page.url string.
Forcing to duplicate it fixes the crash.
