fixes `getRecipient`: using `sender` param instead of calculating sender itself

usually, there is always a sender around `getRecipient` call.
no need to recalculate sender. and more important, in some of
JSON-RPC/GraphQL call, the sender is come from `rpcCallData`,
not from `tx.getSender`. or in ohter situation when the tx is
an unsigned tx, without `r,s,v` fields to calculate sender.
