Transactions API implementation on view wallet page

[scottdonaldau]

Currently transactions do not appear on the view wallet page. Updates are required on the qrl node to enable this functionality.

@jleni See https://github.com/theQRL/QRL/blob/master/qrl/services/PublicAPIService.py

Likely just need try/catch around these bits of GetObject

        if self.qrlnode.get_address_is_used(query):
            address_state = self.qrlnode.get_address_state(query)
            if address_state is not None:
                answer.found = True
                answer.address_state = address_state
                return answer

        transaction = self.qrlnode.get_transaction(query)
        if transaction is not None:
            answer.found = True
            answer.transaction = transaction.pbdata
            return answer

When the above fix is implemented in next chain reset, The getAddressState API should respond with an array of transaction hashes.

Transaction history is now available in view wallet
