* Fixed issue #1126. DefaultCodegen now sets the hasChildren property of CodegenModel when children models are added to the model. Changed the modelGeneric.mustache template to decide whether to include a base validation model (for children to inherit) based on the hasChildren property, and not the discriminator property.
* Run the ./bin/utils/ensure-up-to-date script after fixing the issue #1126
* Reverted modification in go samples, performed by ./bin/utils/ensure-up-to-date, that are failing in CI.
