Fix choregraphie dsl
Fix choregraphie dsl

During commit to support recent ruby we completely broke choregraphie
behavior (not calling the block passed to `choregraphie do ... end`).
This patch fixes it.

The reason we've not seen it is that serverspec validation was not
executed in kitchen 🤦. I'll fix it in a seperate commit.
