Expected Behavior

It seems that lerna run isn't running on packages from a monorepo.
Until v3.13.4 it used to work fine

Current Behavior

It is not working after v3.14.x

Steps to Reproduce (for bugs)

1. Clone this repo
2. Install dependencies yarn
3. Run yarn build > which will create a lib directory on every package
4. Check out if the lib directory has been created for the alert package: /farmblocks/packages/alert/lib
5. Remove this directory
6. Upgrade lerna to the latest version (or v3.14.x) yarn add --dev lerna@latest -W
7. Run yarn build again. The directory /farmblocks/packages/alert/lib should've been created but it was not.
