Andrew Chow 3457679870 Use separate watchonly wallet for multisig in feature_nulldummy.py
Create and import the multisig into a separate watchonly wallet so that
feature_nulldummy.py works with descriptor wallets.

blocktools.create_raw_transaction is also updated to use multiple nodes
and wallets and to use PSBT so that this test passes.
