Current behavior

when deploying the contract fallback function is not displayed alongside all the other functions.

Expected behavior

fallback function should be displayed

Minimal reproduction of the problem with instructions

deploy this contract on qmix.qtum.org:

pragma solidity ^ 0.4.18;

contract testingContract {

    function testingContract() public {

    }

    function () public payable {

    }

    function getBalance() constant public returns(uint){
        return this.balance;
    }

}

only getBalance will be displayed not fallback function

What is the motivation / use case for changing the behavior?

cannot send funds to contract on reg test environment and suspect this issue is related
