SDK: naming convention transform camelCase not working for inputTypes

Bug description

When we use the new naming convention transform with the SDK to transform snake_case types in camelCase, renamed input fields are not well binded with their corresponding snake_case fields.

 transforms:
  - namingConvention:
      fieldNames: camelCase

To reproduce

yarn install
yarn generate:sdk
yarn server:start
yarn client:start
