Type errors after upgrading to v4.0.3

[simonihmig]

The latest version, more specifically this PR, seems to cause type errors when upgrading, at least when using a not so recent Ember version and non-native types.

The published declarations/settled.d.ts file has this as its first line:

export declare const checkWaiters: typeof import("ember-testing/lib/test/waiters").checkWaiters;

This probably works if you have latest native types (idk, I assume), but it fails for us with:

      [types] ../../../../node_modules/@ember/test-helpers/declarations/settled.d.ts:1:50 - error TS2307: Cannot find module 'ember-testing/lib/test/waiters' or its corresponding type declarations.
      [types] 
      [types] 1 export declare const checkWaiters: typeof import("ember-testing/lib/test/waiters").checkWaiters;

I don't think there is a need to expose that checkWaiters type to the outside, it is only used internally, isn't it?

You make a good point -- here is a PR that removes the export: #1503
