Users can view all users and bug fixes

* bugs
* new users location was not being saved
* local controller methode name was wrong
Ah, well how about:

```ruby
def create
  user = sign_up(user_params)
  user.location = find_location

  if user.save
    redirect_to user.location
  else
    @user = user
    @location = user.location
    render :new
  end
end
```
