In the migration to migrate the corresponding name of the partner id to
user agent, part of the requirement was to migrate the partner id
itself if there was no partner name associated. This turned out to not
be so good. When we parse the user_agent column later, it is returning an
error if the user agent is one of these UUIDs.
