siteurl is not necessarily the first row in wp_options.

It appears that other options such as cron can be first.

This removes the option ID from the assertion, as it is not relevant.

We only want to verify that the site URL changed.

Any idea which recent core changeset made changes regarding this?

Not really. Maybe one of the autoload-related changes 🤷
