Fix the searching on admin names and don't search on auth tokens.

The "first_name" and "last_name" columns don't exist on the admin
collection, so this was actually just supposed to search on the "name"
column.

And I'm not sure why we really exposed searching on auth tokens, but
this doesn't seem necessary.
