Yeah, quite annoying for Naruto. Especially considering the fact that Naruto didn't become Jonin until after the events of The Last. Iruka states in the episode that Naruto could become Jonin in about two years, which would be the time that The Last takes place (and yes, he was still a Genin during the events of The Last). He presumably took his test some time afterwards.
