Model name suffix is not included in generated GraphqlJacksonTypeIdResolver

[YarLyashenko]

Issue Description

With options

<generateJacksonTypeIdResolver>true</generateJacksonTypeIdResolver> 
<modelNameSuffix>TO</modelNameSuffix> 

and without model name prefix generated GraphqlJacksonTypeIdResolver does not have suffix:

 @Override
    public JavaType typeFromId(DatabindContext context, String typename) {
        try {
            Class<?> clazz = Class.forName(
                "io.github.kobylynskyi.product.graphql.model." +
                typename
            );
            return context.constructSpecializedType(superType, clazz);
        } catch (ClassNotFoundException e) {
            System.err.println(e.getMessage());
            return null;
        }
    }

Steps to Reproduce

1. Include options generateJacksonTypeIdResolver, modelNameSuffix and exclude modelNamePrefix from configuration.
2. Generate files

Expected Result

Suffix is added to GraphqlJacksonTypeIdResolver.typeFromId()

Actual Result

Suffix is not added to GraphqlJacksonTypeIdResolver.typeFromId(), class could not be found
