duplicate variable names

Duplicate variable names are being generated for [Asana's Open API Documentation](https://raw.githubusercontent.com/Asana/openapi/master/defs/asana_oas.yaml).

If you run the generation with the above linked Open API Document, the function `getProjectStatusesForProject` will have 2 variables with the name `projectGid`. I'm using the default (non-modular) templates, with Fetch http client.
