save_with_edgy hook causes sql exceptions

[choxi]

I have one of the simpler configurations set up

User < ActiveRecord::Base
  acts_as_edgy :like, Like, Item
end

and when I create a new Like(with columns "user_id" and "item_id") I get this exception:

Exception in background thread: SQLite3::SQLException: no such column: users.item_id: SELECT  "users".* FROM "users" WHERE "users"."item_id" = 1 AND ("users"."id" >= 0) ORDER BY "users"."id" ASC LIMIT 1000

I think the Bridges are being constructed incorrectly in Edgy#edgy_build_connection because when I get here. the conditions hash is {:item_id => self.id}.
