Title: Removed the after_initialize callback in old syntax

as specifying the class name as second parameter in
"serialize options, Hash" causes options to always
have the default value of hash (an empty hash)
- see API documentation of ActiveRecord::Base -
so there is no need to call after_initialize
to create an empty hash if none is present.
