* Add test case to reproduce the issue https://github.com/OpenAPITools/openapi-generator/issues/2574 * Fix: an alias of "an alias of simple OAS type" has an incorrect property `isAlias: false` * Use ModelUtils instead of referring the "type" value directly * Delete an unnecessary condition * Tweak: the order of conditions * Fix wrong "isAlias" value on ComposedSchema
