elements-cli unblindrawtransaction cannot unblind own sent payments

Start by reproducing the issue with elements-cli using getrawtransaction, unblindrawtransaction, and decoderawtransaction, comparing the transaction IDs and each output before and after unblinding. Done means unblindrawtransaction preserves the original txid and unblinds every applicable output, including sent payments rather than only wallet-owned outputs.

There are two bugs:

1. unblindrawtransaction method changes TxId of the transaction
2. it does not unblind all outputs, but only those coming back to the wallet (change or deposits)

Have a look:
