One of the bundles is an extender, that publishes a Configuration using Config
Admin. This configuration is picked up by DS to create a new Service using a
ManagedServiceFactory.
At some point in the teardown I seem to be in the state where:
1. The configuration is being deleted because the target bundle is being
uninstalled
2. The Bundle containing the SCR component is being uninstalled
3. SCR is attempting to unregister the managed service because of the
asynchronous notification from config admin.
I'm not sure whether the fault lies with the core framework or with scr, or
with config admin. My guess is that SCR is at fault for trying to unregister a
service for an uninstalled bundle, but that the framework shouldn't be blowing
up either. Config Admin is probably an innocent bystander.
