Does not work with engines

[gossi]

I tried to use decorator-transforms in an engine.

After couple of failing attempts I was able to make it run error-free (in ember s) by setting runEarly: true. Config was primarily set in ember-cli-build.js + tests/dummy/app/app.ts for the global import.

My idea was to use it for some debugging, to have a more modern output to walk through. But transformed code always looked like babel transformed code (no change).

Additional notes:

• Adding the config to index.js had no effect either.
• ember-cli-babel is at version 8.2.0
• After short convo with @NullVoxPopuli it might be a bug in ec-babel and engine interaction
