Can't schedule published by each language.

I agree on the issue. This renders the module completely unusable for our use case.

I created an english article in state Draft, then created a german translation, also in Draft.
On the english (original) node, I set the scheduled publication date, and then when running the cron, both language versions get published.

Additionally, I would rather classify this as major, as this is a core functionality described on the project page which does not work as expected.

The focus of this module is to work with multilingual instance (translated node) and allow to schedule the publish status for each language revision.
