reads identity from ledger in 'wallet:multisig:signature:create' (#5717)

when a user passes the '--ledger' flag to the
'wallet:multisig:signature:create' command they intend to use a Ledger device
to create a signature share. the identity used _must_ be the identity from
the Ledger device, so read the identity from the device instead of from the
walletDB
