Fix broken DictionaryDao.

Moving GetDataObjectFromReader into a helper class broke dictionaryDao, as
it doesn't override GetDataObjectFromReader but does override
SetValueOnObject.

FastDaoJoinReader still needs access to a static version of this method, so
GetDataObjectFromReader is now duplicated in both FastDao and FastDaoHelper
