Navigating history fails during initial app start

[noyainrain]

Navigating back / forward during the initial app start, i.e. with empty local storage, fails with the following error:

[E 191128 18:17:48 server:766] Client error occurred
    TypeError: null is not an object (evaluating 'this._data.settings.title')

To reproduce with Safari:

1. Open Hello in private mode
2. Navigate to About
   (2 history entries, settings set)
3. Restart browser
   (2 history entries, settings unset)
4. Navigate back while Hello is booting

Note that other browsers do not restore private tabs, but the same effect can be achieved by manually clearing site data.
