Fix hardcoded links to `rww.io`

[dmitrizagidulin]

To Reproduce:

1. Pull a fresh copy of profile-editor, copy to a running instance of ldnode and try to edit your own local profile.
2. Click 'Login' link.
3. Click 'With Certificate` button.

Login tries to log into rww.io and fails -- hardcoded references at app/login/login.js#L42 and app/app.js#L573.
