`quickfix.Initiator.Stop` and `quickfix.Acceptor.Stop` should also call `store.Close`

[AlexandrosKyriakakis]

From my pov, when the application (Initiator/Acceptor) stops it should also call store.Close and then when app starts again, it should create a new store using the storeFactory.Create.

Why store.Close is never called?

Based on the code, it seems that the garbage collector handles the cleanup of the store once the session dies
