Scheduling fails for node without content moderation enabled

Problem/Motivation

On a site with Scheduler and Scheduler Content Moderation enabled on only certain node types, scheduling works for those node types, but not for node types still using normal publishing. When the scheduling cron runs, the logs indicate that publishing succeeded, but when visiting the node form I see the node is still unpublished. When checking the database I see publish_on is set, but publish_state isn't, which kinda makes sense, but it seems like this module can't deal with that situation.
