Some leader traits can't be added to Machine councilor node

[openly-retro]

The game literally wont allow it, and clicking the effect deducts a point but wont add the trait

• leader_trait_adaptable_2
• leader_trait_gifted_2
• leader_trait_resilient_2
• leader_trait_adventurous_spirit_2
• leader_trait_educator
