Oracle responses must use the same set of signers as oracle requests even though the transaction itself is signed by oracle nodes/contract. We can probably improve interop.Context by removing Tx field completely and adding more functionality to Container, but it's not very convenient for VerifyWitness and will require adding more stub-like methods for Block, so Tx is used for now (and we do have it in every relevant case).
