Fixes #722

[UnHumbleBen]

This commit seems to forgotten to add formParams for addCodegenContentParameters function

[HugoMario]

hey @UnHumbleBen thanks for your PR, this is something interesting to discuss. Maybe the method needs more refactor. I think form parameters and and body parameters are excluding each others according to :
https://github.com/swagger-api/swagger-codegen-generators/blob/master/src/main/java/io/swagger/codegen/v3/generators/DefaultCodegenConfig.java#L2149-L2191

So based on that:
addParameters(content, codegenOperation.bodyParams);
and
addParameters(content, codegenOperation.formParams);

should be called sequentially?

[UnHumbleBen]

Can you explain more on what the issue is? My understanding is that if there are no bodyParams, then addParameters(content, codegenOperation.bodyParams); does nothing. If there are no formParams, addParameters(content, codegenOperation.formParams); does nothing.

[HugoMario]

yea, you're right, that's what we expect.
