Merge bitcoin#25486: test: fix failing test interface_usdt_utxocache.py

f665c6e test: fix failing test interface_usdt_utxocache.py (Sebastian Falbesoner)

Pull request description:

  The `from_node` argument doesn't exist anymore for `MiniWallet.create_self_transfer` since PR bitcoin#25435 (commit fa8421b), leading to an error on master:

  Fix this by removing the argument. (Unfortunately, the USDT tests don't seem to run on any CI target, I guess that's due to missing permissions to hook into the kernel.)
