Content type export does not contain published default option

Issue

The content type property that represents the whether nodes are by default published, is not exported in config.

How to reproduce the issue:

- Install core (standard profile)
- Edit the 'page' content type
admin/structure/types/manage/page
- Make sure the 'published' option is checked under the 'Publishing options' vertical tab and save
- Export node.type.page
- Un-check the 'published' option the 'Publishing options' vertical tab and save
- Re-export node.type.page
Exports are identical.

Consequence

The node.type.* export doesn't contain a property that represents the default 'published' option of a content type.
This also means that it is currently impossible to move this setting from one environment to another.
