When addres type or change type is not specified, bitcoind will now start with addresstype=bech32m and changetype=bech32m. We take this opportunity to fix feerate tests that failed because of the following reasons: - first of all, we had a bug where we didn't take into account the anchor amount in our fee calculation, so we ended up always adding `330 sats` to the on-chain fees we paid, which was hidden by our tolerance interval, but started appearing with smaller p2tr inputs - then we fix the remaining tests that need manual tweaking of the utxos available in the test wallet, because they end up creating transactions where we don't have a change output (and overpay fees slightly, but not enough to make it worth adding a change output), these tests simply needed to be tweaked to accomodate p2tr weights Co-authored by @sstone
