An in-range update of lodash is breaking the build 🚨

## The dependency [lodash](https://github.com/lodash/lodash) was updated from `4.17.11` to `4.17.12`.

🚨 [View failing branch](https://github.com/konsumer/grpcnode/compare/master...konsumer:greenkeeper%2Flodash-4.17.12).

This version is **covered** by your **current version range** and after updating it in your project **the build failed**.

lodash is a direct dependency of this project, and **it is very likely causing it to break**. If other packages depend on yours, this update is probably also breaking those in turn.
