Remove unused lodash.

[kylev]

libraryManager.ts never actually used it, and nothing else remaining does.

Also corrects missing changes to package-lock.json and a little whitespace.

Looks like part of package-lock.json didn't get committed with 6f6f84a. Like maybe npm i got run after the engines change but not the devDependency bump.
