SomberNight d3227d7489 transaction: for witness v0 txins, put both UTXO and WIT_UTXO in psbt
Until now we have been only putting PSBT_IN_NON_WITNESS_UTXO (="UTXO", full tx)
in segwit witness v0 txins, as signers wanted the full tx anyway due to
bip-143 sighash issue [0], and as WITNESS_UTXO can be calculated from UTXO.

My reading of bip-174 is that either behaviour is correct, but
achow101 said bip-174 expects PSBT_IN_WITNESS_UTXO for segwit inputs.
Regardless, including both fields does not increase the tx size too much
(UTXO can be very large ofc but we were already including that, WIT_UTXO is small).
This also might increase compatibility with some other software - I've found
some issues where this might have been the culprit [1][2][3].
