We need to:

1. See what's in DB before calling callGetInitialReduxState() - based on this we can add params to fetch/skip some store parts.
2. Wait with rendering app until data from DB is read - similar thing as on native.
3. Migrate data if needed - we don't have data in redux-persist like on native, if there is no data in DB we need to get it from keyserver and put into DB.

Depends on D9949

Check if app still loads after refresh, and if persistence (drafts) works.
