In case of an empty `Invocation` script, its parameters will be guessed from

(allowed for main transaction and forbidden for fallback transaction) or of
the form [opcode.PUSHDATA1, 64, make([]byte, 64)...] (allowed for main

pass verification), i.e. to be a placeholder for a notary contract signature.
Both ways are OK for network fee calculation.
- A standard signature witness must have regular `Verification` script filled
even if the `Invocation` script is to be collected from other notary
requests.
