Fix initial only types not evaluated as inital types

[koertho]

This PR fixes the issue that some types, that have no "non-intial option" are not evaluated as initial type.

This covers followig types:

• sql
• published

[koertho]

I also added the published type to this list, as it is also an inital-only type and not evaluated in this method.

I just checked the other elements.

Following I will add:

• skip_parent

I don't know about these elements, if they should also be added, as they are a little special:

• auto_item
• external_entity
• current_member

[koertho]

@Defcon0 @AlexejKossmann What do you think about the other types?

[koertho]

I will merge this as I need it now, but we can discuss further :)
