Fresh repository clone won't test without extra build step

Subject of the issue

When doing a fresh clone of the mdx repository the test and format instructions fail due to /packages/tag not being built.

I do not know if this is specifically related to a Windows development environment. I discussed this with @silvenon and initially we suspected this was related to it being on Windows but the fact that it is related to tag not being built makes me question that.

Your environment

• Windows 10
• MDX latest code
• Node 8.11.2, Yarn 1.12.0

Steps to reproduce

Clone a completely clean instance of the repository. Run yarn followed by yarn bootstrap followed by yarn test.

Expected behaviour

The tests should run.

Actual behaviour

The tests fail with message that @mdx-js/tag cannot be found.

Hotfix

Go to /packages/tag directory and run yarn build. After that the tests run and passes.

@wooorm Sure! tag refers to the @mdx-js/tag library that lives in packages/tag which is causing the fresh install errors when running tests because it requires a babel compilation build step.
