XEEN: Fix aborting combat loop prematurely via bad sleeping check

Previously combat was being aborted prematurely, though it wasn't
noticeable in most casees since the next turn combat started up
again seamlessly. But there were a few edge cases, such as
defeating monsters in a single turn, but having more to the side,
where it resulted in the list of active monsters being fought
being redrawn with no contents
