Commit
This commit does not belong to any branch on this repository, and may belong to a fork outside of the repository.
This commit removes an empty life from `LifecycleManagedBoltFactory` and renames it to `BoltFactoryImpl`. It also adds tests to assert that reference to `TransactionIdStore` is refreshed when factory is restarted.
