Don't pre-build UI deps for unit tests

I know, this sucks. I spent all day trying to get to the bottom of the CI failures that started happening the other day with no luck.

There is something going on with how we were moving the node_modules directory into the source tree from the pre-built location in /tmp. This was working, but then it broke. I hope to cycle back on this sometime next week if I have the time.
