Version Information

Describe the bug
Saga Timeout manager does not have a SagaId property and thats why its not unique.

To Reproduce
Steps to reproduce the behavior:

1. Create a new Saga
2. Add a handler for ISagaHandlesTimeout
3. Instantiate a new saga. The first one works perfectly fine.
4. Instantiate another saga - You will get this error message:
   ERR akka://your-app-system/user/yoursaga-saga] Actor name “BulkActionTimeout-timeoutmanager” is not unique!
   [akka://your-app-system/user/bulkaction-saga/bulkaction-a8ac291a-e157-4ba9-ac99-618d2831dee5#1018278655]: Akka.Actor.ActorInitializationException: Exception during creation
