redux-persist: Problem with SSR on v5

@joturako I have never done SSR but I have a suspicion that if you are using redux persist cookie storage then you actualy do not want the FE to rehydrate at all. Instead you want initial redux state to be initialized with whatever the backend rehydrated from cookies.

Perhaps this is more of a question for SSR in general with redux: how does the server set initial state for redux on the client? I think if I better understood that then we could make it work with the redux-persist api. E.G. one option is to not have redux-persist rehydrate at all, but still write state updates. That would look roughly like:

import { createPersistoid } from 'redux-persist'

// later with store in scope
let persistoid = createPersistoid(persistConfig)
store.subscribe(() => persistoid.update(store.getState())

just published rc.2 with this: https://github.com/rt2zz/redux-persist/blob/v5/src/persistReducer.js#L57-L58

I think that solves the problem
