CI flake: empty chan info

I was able to repro the issue by running:

> retry-success.sh ./scripts/tests/test-ci-all-backcompat.sh v0.2.1
> cat (which retry-success.sh)
#!/usr/bin/env bash

while true : ; do "$@" || exit 0 ; sleep 1 ; done

3 times in parallel, and waiting some time.

The issue seems to be:

00:04:26 2024-04-27T17:36:22.874154Z DEBUG spawn{task_name="JitTry alloc::sync::Arc<()> value"}: devimint::external: Empty chan info edge=ChannelEdge { channel_id: 123145302376449, chan_point: "33ded66d14

which we've seen before.

@fedimint/lightning what can we do about, I remember this issue before, and seems still to be there?
