Two issues: * the templates tree given in `lintTree` seems to be empty in a MU project. I wrapped `tree` (here: https://github.com/ember-template-lint/ember-cli-template-lint/blob/master/index.js#L55) in a `debug()`, which wrote an `EMPTY_MERGE_TREE` * the `ember template-lint:print-failing` fails because of a hardcoded `app/` path: https://github.com/ember-template-lint/ember-cli-template-lint/blob/master/lib/commands/print-failing.js#L21
