[2.0.0-beta.19 and later] Redux example fails with redux-devtools installed

[Zaiban]

When using redux-devtools with 2.0 beta 19 or newer, the app fails with a message TypeError: Cannot read property 'position' of undefined. All previous versions of Next work with no problems.

Minimal reproduction from with-redux repo with DevTools added:

@Zaiban Would it be an option to use this:

Change your initStore to:

export const initStore = (reducer, initialState, isServer) => {
  if (isServer && typeof window === 'undefined') {
    return createStore(reducer, initialState, applyMiddleware(thunkMiddleware))
  } else {
    if (!store) {
      store = createStore(reducer, initialState, compose(applyMiddleware(thunkMiddleware), window.__REDUX_DEVTOOLS_EXTENSION__ && window.__REDUX_DEVTOOLS_EXTENSION__()))
    }
    return store
  }
}

Closing this for now. Feel free to re-open if needed.

I'm aware of the browser plugin, however it is not supported besides FF and Chrome and I have to test on a lot of browsers. Besides that, installing a plugin for every browser just to use the devtools is a pain in the ass while the integrated version just works with no additional work. I do not have enough time at the moment to research this issue further so I leave it closed for now and just disable devtools in my app completely. I will reopen this when I have some spare time to research how to get it working.

The culprit behind to this seems to be 8b94534 from #856
