Scaffolding tests in a new container throws "Error: ENOENT: no such file or directory, scandir 'lib/waves/'"

I was setting up a new container earlier and the following error was thrown when I went to create a new demo test:

➜  mlg git:(master) gulp new --demo w1
[15:40:09] Using gulpfile ~/Documents/mojito-pipelines/mlg/gulpfile.js

When I created a waves folder under lib, it worked fine though. I think the scaffolding feature needs to create the waves folder if it doesn't exist (a probable scenario for new users).
