Add instruction to run ember build and ember test

[jrhorn424]

Before running ember server.

Do you want to add this as an instruction in the README, or automatically run them via grunt when the server is run?

[gaand]

I don't think we want to run them automatically. We don't do that for any other template.

We don't currently use grunt server for this. I'm not sure we should. We're using ember-cli and should probably configure it if possible.

[raq929]

OK. I'm confused about what we are configuring it to do.

[gaand]

Me too.
