We now essentially do 2 redirects if you hit a `folder/`
1. If you visit `/ui/dc1/kv/folder/`, `consul` will redirect you to `/ui/dc1/kv/folder`
2. Once redirected to `/ui/dc1/kv/folder` via a 301, use ember/history
API to redirect you back to `/ui/dc1/kv/folder/`.
Bit long winded, but achieves what we want without having to get stuck
into `consul` itself to remove the 301 for the UI
