Change nukeSet() from public to internal

[Conviley]

I'm using Truffle V5.1.13 and in my contracts pragma solidity ^0.5.1; Having nukeSet be public causes truffle tests to fail with the following error message

    "before all" hook: prepare suite: TypeError: Cannot read property 'typeClass' of undefined

Changing nukeSet() to be internal allows tests to go through
