    yelp-view: Update current page information when loaded from history cache
    
    When a page is loaded from the history cache, the URI is not resolved
    and the metadata is not updated. Check in policy callback if the action
    is a back-forward navigation and resolve the URI in that case but
    without loading the page once the URI is resolved, since the page will
    be loaded from the history cache.
