Vocabulary management broken for Scalars

[sanketshevkar]

Bug Report 🐛

Expected Behavior

Should be able to add vocabulary annotations for Scalar Declarartions

Current Behavior

I was testing the vocab file generated by the code generator I've written. While testing it on this repl https://replit.com/join/xeqmqanuuo-sanketshevkar
I'm not able able to add a command set to the model manager when any scalar value is present in the .cto file. In other cases it's working fine.
I am getting the following error.

TypeError: decl.getProperties is not a function
