When converttopsbt is called with a signed transaction, it either fails with "TX decode failed" if one or more inputs were segwit, or "Inputs must not have scriptSigs and scriptWitnesses" otherwise.
Since no effort is made by the test to ensure the inputs are segwit or not, avoid checking the exact message used.
The error code is still checked to ensure it is of the correct kind of failure.

The final check for extraneous sigdata has a flipped boolean, resulting in incorrect behavior.

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.

Added functional tests for PSBT that test the RPCs. Also added all
of the BIP 174 test vectors (except for the updater tests) in the
functional tests.
Added a Unit test for the BIP 174 updater test vector.
