Update mocked submitRedemptionProof fn\

Add `redemptionTxHash` param it should be a Bitcoin testnet transaction
hash(byte order corresponds to the Bitcoin internal byte order) that was
made from a given wallet to a given redeemer output script. Thanks to
that we can find the tx on the Bitcoin chain and display data in the
dapp.
