`failBuild` needs to be passed to `getNextConfig`

[ascorbic]

In several places we are calling getNextConfig without passing it utils.failBuild. This means that any error uses the default handler, which throws an error and is reported as a plugin error. We should pass the util into the NoN runner and pass it through to all of ther functions that need it. Alternatively we should just pass the config through isntead.
