fix Address.utxo integration test

[christroutner]

The integration test for Address.utxo() is failing because the address it uses for the test have no utxos. This is the address:

bitcoincash:qrdka2205f4hyukutc2g0s6lykperc8nsu5u2ddpqf

The scope of this task is to:

• Create a new wallet and fund the first address with 1000 sats.
• Replace the current address with the new address in the Address.utxo integration test.
• Destroy the wallet so the UTXO will never be spent.

I am funding the above address with 1000 sats to keep the test functioning until it can be fixed. I have no way to know when/if the UTXO will be spent.
