[python] Fix permission error when create related objects (#11783)

after we add permission to our codebase in dev branch, will got error
when create objects from pydolphinscheduler, because users with user_id
equal to `Integer.MAX_VALUE` is ordinary users which can not have access
to create unless we grant permission to the role manually. this patch
change dummyUser to admin user's user_id == 1 to fix it
