postinstall script

[emilyb7]

So after pulling down all of the latest stuff today, I tried to npm install again and it's throwing errors. The Nightwatch tests are running before selenium and env2 are installed.

I've got round this by installing all the packages one by one. Just wanted to make a record of this in case it causes us problems in the future.

Good shout recording it 👍 , it's likely to come up again on future deployments so we should investigate, can you add screenshots/copy paste console errors here?
