[Seaside] [Bug][2.8] WAUserConfiguration-#initialize migration problems

[Keith Hodges]

In loading Seaside 2.8 into an image which has 2.7 in it, the 
WAUserConfiguration-#initialize method is copying over values for its 
ancestors which are references to ObsoleteClasses.

It appears that performing an initialize or a WADispatcher resetAll, 
essential fails to reset the configuration ancestors, it just propagates 
any previous errors that might be present in the configuration ancestry.
