Bug

### What is the current behavior?

When trying to reading the state from redux after saving it in redux, I have :

```jsx
index.js:1 Warning: Cannot update a component (`Title`) while rendering a different component (`FormSpy`). To locate the bad setState() call inside `FormSpy`, follow the stack trace as described in https://fb.me/setstate-in-render
in FormSpy (at FormStateToRedux.js:8)
in FormStateToRedux (at CreatePromotionForm.js:308)
```

### What is the expected behavior?

I expect no erros

### Sandbox Link

Just use a component that is having

```jsx
