Don't force user to create ICustomCollectionMapperFactory if using custom NH user collection type
Description
If user has custom NH user collections, currently user needs to create an ICustomCollectionMapperFactory even if envers "normal" handling of collection (list, bag, set) is enough.
If user wants to override how Envers treats the collection he can still create he's own ICustomCollectionMapperFactory.
