Contest listing should always show submission status

[pishifat]

relevant because someone thought they submitted a map to https://osu.ppy.sh/community/contests/227, waited a month for results to come out, then discovered that their entry wasnt counted because it was deleted (accidentally, i assume)

i think it shows submission status if "voting" is not ended, but none of these contests use voting anyway, so it's in a bit of an awkward place. showing the same submission status before and after voting concludes might be an ok solution here
