rpc, tests: in utxoupdatepsbt also look for the transaction in the txindex

Browse Source 
Previously only the segwit utxos being spent by the psbt were looked for and
added to the psbt. Now, the full transaction corresponding to each of these
utxos (legacy and segwit) is looked for in the txindex and mempool and added
to the psbt. If txindex is disabled and the transaction is not in the mempool,
then we fall back to getting just the utxo (if segwit) from the utxo set.
