Fix restore_from_log panic on Thinking entries, fix bail nullglob

restore_from_log called .message() on all entries including Thinking
entries, which panic. Filter them out alongside Log entries.

Also fix bail-no-competing.sh: without nullglob, when no pid-* files
exist the glob stays literal and always triggers a false bail.
