"yarn test" fails sometimes #5
Description
When installing the project using yarn sometimes babel-core@6.x instead of babel-core@7.0.0-bridge.0 is installed, causing the unit tests to fail.
This seems to be related to how jest-config, etc. has set up their dependencies.
I've tried various different solutions posted online, but none to avail. The strangest thing is that sometimes it works, then you go into a different directory, repeat the same steps, and things stop working. (Even with yarn cache clean beforehand)
This issue does not happen in NPM.
I'll go ahead and mark yarn as unsupported for now until either I or a super awesome contributor can figure this out.
