Github checks: updated only once all jobs are done

If I’m not mistaken, the Github Checks are only updated once all jobs are over.

This forces to come to check the Travis page in the meantime, therefore makes the Github Checks integration much less useful :slightly_frowning_face:

I don’t know yet what parts of Travis are open-sourced (I can’t check 200+ repos randomly :smile: ) but it’s definitely on such issues that I’d happily contribute and look for a fix.
