Description

When built-in objects' labels change, this sometimes affects test outputs downstream. This MR contains several changes caused by such a situation. We should either isolate these tests from trivial upstream label changes or make it easy to regenerate the outputs (e.g., with --regenerate-output, as we do elsewhere in this repository).

Desired behavior/Acceptance criteria (returned value, expected error, performance expectations, etc.)

• test flake, or its consequences, are reduced
• there is a way to regenerate these test outputs easily, or the test outputs don't need to change due to upstream changes
