Fireplace tests have been broken for a while, since https://github.com/mozilla/fireplace/commit/e5aa13992417e26466c94e72b7295b92c37312b8 according to travis history (https://travis-ci.org/mozilla/fireplace/builds) Let's fix that.
Pretty sure https://github.com/diox/flue/commit/08fe44f6d57638e2c4a2f2b6d7df530736e8f60f will fix it - it fixes the failures for me locally. We just need to update the flue instance on stackato and get npmjs.org to stop returning 503s...
We also needed to wait a bit after logout: https://github.com/mozilla/fireplace/commit/71732a508a424bb37dbbf96d8ecf7cfa253d0cdc
Fixed for good in https://github.com/mozilla/fireplace/commit/50cca27cf3cf5353c299500d81b13b6b1906902b
