Improve test coverage of kayaRPC

[edison0xyz]

More testing vectors have to be introduced.

Test coverage for the CreateTransaction has been limited so far. Help needed to have more test cases to ensure correctness of CreateTransaction with smart contract. Payments testing has already been done under tests/transaction.test.js, but more vectors are welcome.

Currently only 50.87% of the lines have been covered under test case. Will be good if we can have 80% coverage since smart contract transaction is a significant portion of the code.
