NeonTxSender raises "Operator has NO resources!"

[rozhkovdmitrii]

In the test_03_validate_execution_when_not_enough_sols_for_all_operator_accounts we suppose that NeonTxSender doesn't raise RuntimeError "Operator has NO resources!" anymore. That's why we suppressed catching for this exception during self.testee._validate_execution()

       with self.assertLogs('neon', level='ERROR') as logs:
            >>> # with self.assertRaises(RuntimeError): <<<
            self.testee._validate_execution()
            print('logs.output:', str(logs.output))
            self.assertRegex(str(logs.output), 'ERROR:neon.Proxy:Operator account [A-Za-z0-9]{40,}:[0-9]+ has NOT enough SOLs; balance = [0-9]+; min_operator_balance_to_err = 1049000000000000000000000000')

The issue is in that this call keeps raise this exception and we have to investigate the reason why and get rid of this properly.
