Fix unused parameter in generated code which caused TS errors for use…

…rs of the package. (#613)

When using the default behavior (ie: config `rawRequest` as `false`), the generated code has a `E` unused variable which make TS yelling when TS options `noUnusedParameters` is `true`.

The fix is put that variable onlye when `rawRequest` is `true`.
