YARN needs a modern version of NodeJS and if we don't use the role
to get the latest version, we end up failing on most platforms that
ship an old version of it.
This patch also adds testing to validate that ensure-yarn alone works.

The role previously conditionally installed YARN only if there was
a yarn.lock. The role shouldn't conditionally decide to install
if there is a yarn.lock file as that's not expected behaviour.

This patch refactors ensure-yarn to use the new generic role
to allow it to be cross-platform in the future.
