There are error messages in CI

• [ ] unexpectedly found "\n " when slicing source, but expected "class" Is this coming from ember-cli-htmlbars? Is this related to their recent fix allowing console messages to come through? It sounds like it’s related to AST processing (which we also do), so maybe we have an issue somewhere there.

  Tracking: https://github.com/emberjs/ember.js/issues/19392

• [ ] Errors when cleaning up after tests Tracking: https://github.com/ember-cli/ember-try/issues/813
