"Start a group" not redirecting correctly

[taoeffect]

Problem

With latest changes in #155 (commit eb64870).

Multiple issues with "Start a group":

1. Clicking "Start a group" highlights "New User" menu item instead of "Start a group" EDIT: Err, I guess this makes sense since we're on the SignUp view.
2. Proceeding with "Sign Up" results in error. Tried this twice, screenshots from both attempts:

Meanwhile, the server console outputs:

Running "watch" task
Waiting...
Gruntfile.js: loading file with babel support: ./backend/index.js
API server running at: http://Alice.local:3000
Debug: handler, error

Solution

1. Clicking "Start a group" should highlight "Start a group" tab/menu
2. Clicking "Sign Up" should redirect to group creation screen. Right now it's trying to load localhost:8000/user/ for some reason, and it also fails to load even that.

Added label Kind:Test: Should probably create a test for this as well so that we can automatically check this for correct behavior in the future.

It is not redirecting to the localhost:3000/user/ but failing to make the xhr request to the backend at that route due to it being removed. It now fails the CORS request. It should redirect correctly once a new login scheme is created.

Fixed in #186
