Upsert inserts another row in Rails 4.0.2 w/ sqlite3

For sqlite3 problem with rails 3.2.16 see below: https://github.com/seamusabshere/upsert/issues/19#issuecomment-34584714

In rails 4.0.2:

➜  ~  sqlite3 --version 
3.7.17 2013-05-20 00:56:22 118a3b35693b134d56ebd780123b7fd6f1497668
➜  upsert-demo  ruby -v
ruby 2.0.0p247 (2013-06-27 revision 41674) [x86_64-linux]

Lets generate a 4.0.2 application:

rails new upsert-demo
cd upsert-demo
echo 'gem "upsert"' >> Gemfile
echo 'gem "rb-readline", "0.4.2"' >> Gemfile
bundle
rails g model try i:integer s
rake db:migrate
rails c

Upsert creates the first row successfully. When updating the same record, it duplicates it:

irb(main):005:0> u= Upsert.new Try.connection, Try.table_name 
=> #<Upsert:0x007f2b9a441b88 @table_name="tries", @flavor="Sqlite3", @adapter="SQLite3_Database", @connection=#<Upsert::Connection::SQLite3_Database:0x007f2b9a45cb90 @controller=#<Upsert:0x007f2b9a441b88 ...>, @metal=#<SQLite3::Database:0x007f2b9a426b58 @tracefunc=nil, @authorizer=nil, @encoding=nil, @busy_handler=nil, @collations={}, @functions={}, @results_as_hash=true, @type_translation=nil, @readonly=false>>, @merge_function_class=Upsert::MergeFunction::SQLite3_Database, @assume_function_exists=false>
irb(main):006:0> u.row({i: 1},{s: "String1"})
[upsert] PRAGMA table_info("tries")
[upsert] INSERT OR IGNORE INTO "tries" ("i","s") VALUES (?,?) with [1, "String1"]
[upsert] UPDATE "tries" SET "i"=?,"s"=? WHERE "i"=? with [1, "String1", 1]
=> nil
irb(main):007:0> Try.all
  Try Load (2.4ms)  SELECT "tries".* FROM "tries"
=> #<ActiveRecord::Relation [#<Try id: 1, i: 1, s: "String1", created_at: nil, updated_at: nil>]>
irb(main):008:0> u.row({i: 1},{s: "String2"})
[upsert] INSERT OR IGNORE INTO "tries" ("i","s") VALUES (?,?) with [1, "String2"]
[upsert] UPDATE "tries" SET "i"=?,"s"=? WHERE "i"=? with [1, "String2", 1]
=> nil
irb(main):009:0> Try.all
  Try Load (0.6ms)  SELECT "tries".* FROM "tries"
=> #<ActiveRecord::Relation [#<Try id: 1, i: 1, s: "String2", created_at: nil, updated_at: nil>, #<Try id: 2, i: 1, s: "String2", created_at: nil, updated_at: nil>]>
