Wrong competition logo in Featured Benchmarks on the main page

[ObadaS]

Hello,

The wrong competition logo is displayed in Featured Benchmarks on the main page of Codabench.org.
It seems to consistently affect a few competitions.

The correct logo is shown when opening the competition page.
Some examples :

https://www.codabench.org/competitions/2239/
https://www.codabench.org/competitions/2296/
https://www.codabench.org/competitions/2319/
https://www.codabench.org/competitions/2914/
https://www.codabench.org/competitions/2309/

I can't reproduce the bug on the test server, but there are much fewer competitions there, and it seems to be a rare/specific bug, so it might not have happened there yet.
