Merge #14689: Require a public key to be retrieved when signing a P2PKH input
6b8d86ddb8 Require a public key to be retrieved when signing a P2PKH input (Andrew Chow)
Pull request description:
If we do not have the public key for a P2PKH input, we should not continue to attempt to sign for it.
This fixes a problem where a PSBT with a P2PKH output would include invalid BIP 32 derivation paths that are missing the public key.
