If [XEngine] ScriptStopStrategy is changed between abort and co-op, for the existing session use the previous strategy for that script rather than not starting the script at all. 

We have to do this since we can't unload existing DLLs if they're all in the same AppDomain.
But we can still update the underlying DLL which will be used in the next simulator session.
