Leonard Lyubich 8fc1505351 [] ir: Read addresses of contracts from the client wrappers
After recent changes morph client wrappers provide contract address getter.
It can be used to compose notification parsers and handlers.

Use `ContractAddress` method in constructors of notification parsers and
handlers. Remove no longer used script hash parameters of event processors.
