ui: HTTP Body testing (#7290)

* ui: Test Coverage Reporting (#7027)

* Serve up the /coverage folder whilst developing

* Upgrade ember-cli-api-double now it supports passthrough per url

* ui: make env into a service and use it where we need to be injectable

* Give http/client a body method so we can use it on its own for testing

* Add test helper for testing with and without nspaces enabled

* Add two tests, one thay needs nspaces and one that doesn't

* Keep cleaning up client/http, whilst figuring out a immutable bug

* Convert tests to new return format ([actual, leftovers])
