Oops, fix bug that would sometimes flip own/want in the item bulk menu

If your first wanted list was created before your first owned list,
then `false` would come before `true` in the keys of
`current_user_lists`.

I both fixed this to be more consistent at the model level, because who
likes unpredictable behavior? But also downstream at the view I
hardcoded that true should come before false, because that's a UI
concern that I want to be encoded in the view regardless of what's
upstream.
