Show empty podium for events instead of not showing event at all

[Mollerz]

An issue we ran into at Weston-super-Mare Open 2019 was quite funny. For Skewb and Square-1 we had both events as a Combined Final. However WCA Live auto-deletes competitors from previous rounds upon opening a subsequent round. Because of this, we did not manually remove the no-shows for these events. When it came to the award ceremony, it was exclaimed that we had missed out Square-1 and Skewb and we realised the reason immediately.

I think once the first event has been completed, it would be good on the podium page to just show something along the lines of "Undecided: Final round still in progress!" under the events that don't have finalised rounds to avoid missing events.
