BUG: End up with `1 resolved, 1 installed.` without any duplicate files:

[ryan-roemer]

Have no duplicates and only one installed module.

htmlparser2 (Found 1 resolved, 1 installed. Latest version 3.9.2.)
  3.9.2
    ~/htmlparser2
      * Dependency graph
        my-app@0.0.1 -> enzyme@^3.6.0 -> cheerio@^1.0.0-rc.2 -> htmlparser2@^3.9.1
        my-app@0.0.1 -> react-html-parser@^2.0.2 -> htmlparser2@^3.9.0
      * Duplicated files in static/chunks/commons.HASH.js

Possibly because source of two other duplicates?

Task

• [x] Create regression test if possible
• [x] Identify what's gumming things up. Maybe htmlparser2 being in the path of two ultimate duplicate packages / skews?
