Update sessions/sessiondb/badger to its latest version and SessionController is able to initialize itself if session manager is not provided by the caller-dev.

Changes:

Update the badger database using transactions, as supported from yesterday via: 06242925c2

Add a custom `OnActivate` via mvc/activator/activate_listener.go, this can be used to perform any custom actions when the app registers the supported Controllers. See mvc/session_controller.go for the excellent use case.

errors.Reporter.AddErr returns true if the error is added to the stack, otherwise false
