Another Flaky Test

[benalleng]

I spotted another flaky test in https://github.com/payjoin/rust-payjoin/actions/runs/22503935526/job/65197800039

error: Cannot build '/nix/store/jsfakccg81xlnflph7bsrab4jibpmhv4-payjoin-workspace-nextest-msrv.drv'.
       Reason: builder failed with exit code 100.
       Output paths:
