Added in the task display of the list of identifiers of subtasks. Rest api GET /issues.[format](json, xml)
Welcome, I recently started using redmine via rest api, when requesting GET /issues.[format] redmine sends a list of tasks, each task contains a parent ID, if any, but no child ID, which is not very convenient. I fixed the code. Now the list of subtasks ' IDs is also displayed in the tasks during the query.
