Remove predictable ordering hack from sumeragi

[mversic]

This was introduced in #4263 to prevent consensus from operating if there is a bug in the implementation. We should make sure that consensus operation is well covered with tests and remove this backdoor

[Erigara]

Going to be removed in #4518

I see in the code that that hack has been removed and it looks like iroha has been running successfully without it. But I can't understand if the sorting of peers has become unpredictable, which seems to be the main problem why this task was opened.

this is ok, we can close it
