Fix retrieval of revert reason by using the same weiAmount in the call.

[alexdupre]

What does this PR do?

It fixes the retrieval of the tx revert reason, by using the same weiValue amount that was used in the failed transaction.

Where should the reviewer start?

Consider this simplified test case contract:

contract Test {

    function test(uint n) external payable {
        require(msg.value > 0, 'msg.value must be positive');
        require(msg.value == n, 'msg.value must be equal to n');
    }
}

Then call it with n == 2 and weiAmount == 1, and you'll get a super misleading msg.value must be positive error message.

Why is it needed?

Because it drove me crazy for 24h to debug a complex smart contract when the thrown errors were in completely different code locations.
