Edit SurveyRecord model to not make use of different Survey property for each subclass.
This does mean that a simple query needs to be constructed by hand whenever you want to query for every SurveyRecord for a specific Survey. However the naming is now the same over each SurveyRecord and it fits well into the rest of the design of Melange.
