Test `ratman::router::matching_payloads` will sometimes hang forever
The test in question is here: https://git.irde.st/we/irdest/-/blob/develop/ratman/src/router.rs#L199-235
It's not very complicated, i.e. doesn't rely on any external system that could be timing out. I assume this is a weird race condition but I don't know where and why it happens.
It means that sometimes our CI pipeline will fail even though it shouldn't. Re-running the pipeline usualy fixes it.
