Navigation::canGoForward can cause a crash.

Reviewed by Rupin Mittal.
The Navigation.canGoBack/canGoForward properties can be accessed when we don't
have a current index.
This adds a check to see if the optional value is engaged before we try to
dereference it.
No tests as there's no new behavior.
