fix: build method parameters while generating controller

[aaqilniz]

With my PR here, I enabled the openapi generator to create the controller. That implementation has a bug that ultimately generates buggy controller code in case there is a method parameter with a hyphen (e.g. access-token).

This PR fixes that by properly building the parameter.
