Fix live-restore w/ restart policies + volume refs

Before this change restarting the daemon in live-restore with running
containers + a restart policy meant that volume refs were not restored.
This specifically happens when the container is still running *and*
there is a restart policy that would make sure the container was running
again on restart.

The bug allows volumes to be removed even though containers are
referencing them. 😱
