nil user_stats for fresh User

[JoeCohen]

Lately /user/nnnnnn throws errors for brand-new users. Example below. This is reproducible locally:

• logout
• create a new account
• verify the account (find the verification email via grep verify log/development.log, go to the indicated url.)
• Show the new user.

Note that the user_stats table allows null values for the languages, bonuses, and checklist columns.

@nimmolo: Off the top of your head, do you think this is related to recent changes to site & user stats? (Cf. #2080)

• If not, I'll dig into it.
• If so, could you see if you can fix it?
