reads identity from Ledger in DKG round3

when running DKG using a Ledger device we must use the identity from the Ledger

reads the identity from the Ledger device during DKG round3 instead of from the
walletDB when using the '--ledger' flag in 'wallet:multisig:dkg:create' and
'wallet:multisig:dkg:round3'
