Final ranking should not be visible until the `REVIEW` phase is closed for the challenge

[bountyC0d3r]

New Submission tab is showing Final ranking of the members before the Review phase is closed, which should not be the case.
It should be masked like we do with the final score

@ThomasKranitsas @dushyantb @sushilshinde

Final score is displayed as 0 for this challenge. Can you please check?

(When I checked the same challenges which I previously verified, they have the right score. Seems like the newly updated Final Scores are not updated correctly)

Confirming that this is still an issue

@dushyantb did you had chance to check on this, as discussed the other day ? Do we want to move old challenges to new structure ?
