Errors with Ember v3.22

See original GitHub issue

Just tried upgrading an app to Ember v3.22 and started getting some errors in changeset.

index.js:172 Uncaught (in promise) Error: Assertion Failed: You attempted to update `_changes` on `changeset:[object Object]`, but it had already been used previously in the same computation.  Attempting to update a value after using it in a computation can cause logical errors, infinite revalidation bugs, and performance issues, and is not supported.

`_changes` was first used:

The same happens with _errors as well.

Version

changeset v 3.8.2 (also tested with latest version but same occurs. ) ember v 3.22

@sinankeskin 👋 This is similar to this case. You might have to adjust when/how the changes is created then updated. The problem is something was read-then-written in the same computation in the same “tick”.
