    "goroutines": 11,
    "status": "ok",
    "version": "1.4-d99f37c"
}

Steps to reproduce:

1. go to https://find.dev.mozaws.net/
2. Click [Sign in]. You should be taken to https://accounts.firefox.com/oauth/signin?client_id=29a17a3a31483c8b&scope=profile%3Aemail%20profile%3Auid&state=303a47654010733580c963bf5cb32f7c
3. Sign in. (You should get redirected to https://find.stage.mozaws.net/)

   Actual results:

Upon successful login, I'm taken to https://find.stage.mozaws.net/ (and not find.dev.mozaws.net which I was originally on).

Expected results:

Kick me back to dev server. We're crossing streams which makes it hard/impossible to log in.

I updated the fxa-dev config for FMD. We'll need to get the dev environment reconfigured to use fxa stable dev.
