These shouldn't ever be null, but we have some bad data in production
for prober TLDs left over from the Registry 2.0 transition. Ignoring
null values here is required to finish cleanup for this old data, which
currently cannot even be deleted because it's throwing an NPE when
trying to update these values.
This commit will be reverted after the bad data is cleaned up, likely
sometime next week.
