Handle more states during refresh

We were preserving ContainerStateExited, which is better than
nothing, but definitely not correct. A container that ran at any
point during the last boot should be moved to Exited state to
preserve the fact that they were run at least one. This means we
have to convert Running, Stopped, Stopping, Paused containers to
exited as well.
