fix: We shouldn't show error message in the end of a proposal

[bonustrack]

We should trigger the request in background without showing the error message, we can show the result directly. We should also have a way to not trigger calculate multiple time if few people request it in same time.

You mean the "results are calculating" message?

Actually, with snapshot-labs/snapshot-sequencer#273 we still show an error message at the end of proposal, we need a background task, either on sequencer of webhook to trigger score calculation on proposal end

Should already be a webhook task to trigger the computation on proposal end, to sequencer.

This pr is in case the first computation fail
