Restored rooms wake their automatons

The bot pump only ran when a command or join arrived, so a server
restart landing mid-bot-turn left the restored room waiting forever
for a human to poke it — room 928D sat exactly there, its automaton
holding a perfectly answerable stack. Boot now kicks the pump for
every restored still-running room, two seconds after restore.
