Incorrectly expects the argument to `async-await` to be an array

Looks like I can overwrite this:

declare module 'ember-typed-templates' {
  interface GlobalRegistry {
    'async-await': <T>(params: T | Promise<T>) => T;
  }
}

I'm still not sure why it's the default.

I think I misunderstood how this works.

@wagenet if you have correct typings for this helper - we could add it to repo
