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
This enables people to enter things using the mouse to paste for
example, plus possible other things.
As an aside it also answers my query regarding `fillIn` for testing,
nothing needs to be actually _typed_ anymore! Doh
