Run 'clean' before build

[agibson-godaddy]

Summary

This update sthe workflow to run npm run clean before building. It seems occasionally when running npm run build the coffee assets aren't being compiled. This can be seen by looking at the commit column -- notice how some weren't changed!

After local testing I was able to reproduce those files not changing. They only finally changed by running npm run clean prior to building.
