Remove some responsibilities from action

[renancarvalho]

Hi :)

I think that would be really nice if keep the handling errors in the component itself and remove it from the actions https://github.com/mxstbr/login-flow/blob/master/js/actions/AppActions.js#L195

I'm working on a PR for that, and what I'd like to propose is something like:

• Dispatch and action like 'invalid_login' or something. ( I'll think a better name )
• Subscribe to reducer and update the component based on the reducer state(in this case 'invalid_login')

The main idea is remove the DOM manipulation from the action.

Does it make sense?

Surely it makes sense.
Actions must not receive any logic.
