We made a change to improve the performance of publishing a review by
limiting what fields we were writing on a ReviewRequest. However, we
weren't including "last_updated" in the list of fields, which meant that
a review request with a new review wouldn't jump to the top of the
dashboard. Adding that field to the list fixes this.

Published a review on a review request and saw that the Last Updated was
changed. The dashboard showed "0 minutes ago".
