Consider removing source from Transfer instructions

[dima74]

Consider transfer instruction, e.g. Transfer<Account, DomainId, Account>. It checks that source (provided by ISI) equals domain owner (as stored in blockchain):

iroha/crates/iroha_core/src/smartcontracts/isi/domain.rs

Lines 362 to 366 in e0ff842

	if domain.owned_by != source {
	return Err(Error::InvariantViolation(format!(
	"Can't transfer domain {domain} since {source} doesn't own it",
	)));
	}

Consider removing source from ISI and using domain owner directly. Also applicable for CLI (e.g. even if we will keep source in ISI, we can remove source in CLI)

To update the ownership of an object, the object id and the new owner id should be sufficient arguments. So struct Transfer<S, O, D> enforces unnecessary invariant checks for ownership changes

Yeah, every Transfer<S, O, D> can change into Transfer<O, D>, including numeric asset transfers, which can be considered ownership changes for partial balances (O = Asset)
