…ncing IsTaskDirty assumed that if a task had a SpecVersion, the corresponding service must also have a SpecVersion, since that is where the task's field is copied from. However, there are mixed-version scenarios where a service could get updated by a manager running an older version of swarmkit than the manager that created the task. Add a check to avoid a crash in this case. Signed-off-by: Aaron Lehmann <aaron.lehmann@docker.com>
