fix(diff): properties from ChangeSet diff were ignored

[bergjaak]

Issue # (if applicable)

Closes #29731

Reason for this change

• Diffs that are only present in the change set are ignored

Description of changes

• Include changes to properties that are only present in the changeset

Description of how you validated changes

• Here is an image of what the change looks like, with the fix on the right and the old behavior on the left. I did this with a CDK app that is the same as given in the example from the customer who opened the issue (29731), but the app also includes a new queue (which is in the left and right).

• manual, unit, and integration tested. Ran all integration tests that mention cdk diff:
