IFDB Recommends will recommend buried games

[dfabulich]

In a dev environment, run this SQL query:

insert into unwishlists (gameid, userid)
select games.id as gameid, '0000000000000000' as userid
from games where flags != 1;

When we bury a game we set games.flags to 1, FLAG_SHOULD_HIDE in util.php. This query marks all games in the DB as "Not Interested" except for the buried games. (I encountered this organically as I was impersonating a user.)

Login as ifdbadmin and view the "IFDB Recommends" section of the home page.

Actual: IFDB Recommends will recommend buried games.
Expected: IFDB Recommends should never recommend buried games.
