Sort people by last name is literal

The sorting of people by last name is literally that, and there doesn’t seem to be a secondary sort on first name, as one would normally expect. This means if there are a large number of same last names you have to look harder for the person than you might expect.

I haven’t been able to find any other report of this issue, so perhaps isn’t an issue for others, but I noticed it very quickly once I got into face tagging.

Hopefully something easy to fix.
