AbstractMessageGroupStore.persistentMessageGroupFactory is not overridable while AbstractMessageGroupStore.messageGroupFactory is

[bratwurzt]

Expected Behavior

When implementing custom PERSISTENT MessageGroupFactory, I'd like to override persistentMessageGroupFactory the same way as I can override messageGroupFactory

Current Behavior

AbstractMessageGroupStore.persistentMessageGroupFactory is final and fixed to type of SimpleMessageGroupFactory and can't be overridden
