These tests sometimes fail because sometimes a different amount is shielded (3 vs 3+fee)
which makes the expected amounts of sendAmount and donationAmount incorrect. The code
to calculate donations seems to work correctly but the tests need a bit more improvement.
When the tests pass:
DEBUG:RPC:<-43- {"remainingUTXOs": 1, "remainingValue": "3.00010000", "shieldingUTXOs": 1, "shieldingValue": "3.00000000", "donation": 5, "opid": "opid-868c81ad-885b-42b4-af85-dafa54e695a2"}
When they fail:
DEBUG:RPC:<-43- {"remainingUTXOs": 1, "remainingValue": "3.00000000", "shieldingUTXOs": 1, "shieldingValue": "3.00010000", "donation": 5, "opid": "opid-143309b6-e25a-45d6-9c0c-311f1f61de78"}
