The code attaches global properties to the sandbox context by iterating over all the enumerable properties of `global`. However, in node v10, `console` switched [to being non-enmuerable][1]. This means that for users of this library with node>10, any `console.log`s in evaluated scripts will fail. This commit fixes this issue by manually attaching console to the sandbox (when globals are being used). A test has been added. Prior to the change to eval.js, the test would pass in node v8 but fail in v10 and v12. Also, the tests were already failing in v12, because in v12 `process` also became non-enumerable. I've applied a similar fix to `process` to ensure that it's always available too. [1]: nodejs/node#17708

The `eval` dependency has a bug in node v10 and above, where the `console` won't be available to scripts, even if globals are supposed to be available. See: pierrec/node-eval#18. For users of static-site-generator-webpack-plugin, this means that index scripts which contain logging statements will not work properly. The bug is fixed in eval v0.1.4, so we just need to update the dependency. Test plan: `yarn test` still passes.
