rpcclient: make Notary Actor follow the request creation doc

Browse source 
All Notary contract witnesses in incomplete transaction (both main
and fallback) may either have invocation scripts pushing dummy signature
on stack or be empty, both ways are OK. Notary actor keeps main tx's
Notary witness empty and keeps fallback tx's Notary witness filled
with dummy signature.
