Title: Tiny fix for rails4

Consider a serializer class for a field containing an hstore. With ActiveRecord::Coders::Hstore it could look like this:

```ruby
class CustomHstore
def self.load(value)
hash = value.from_hstore
# Do something with hash
hash
end

def self.dump(value)
ActiveRecord::Coders::Hstore.dump(value)
end
end
```

Since Rails 4.0 it turns into

```ruby
class CustomHstore
def self.load(hash)
# Do something with hash

hash
end

def self.dump(value)
value
end
end
```
