### Description

Path suggestion doesn't work. I have completely removed atom and all configuration files to make sure it is not related to any preference or other installed package, but it still persists.

### Steps to Reproduce

1. Open any file in Atom
2. Type a variable with a path, e.g., `dir='/somedir/'`

**Expected behavior:** Suggesting content of the path

**Actual behavior:** Nothing

**Reproduces how often:** 100%

### Versions
Atom : 1.19.6
Electron: 1.6.9
Chrome : 56.0.2924.87
Node : 7.4.0
apm 1.18.4
npm 3.10.10
node 6.9.5 x64
python 2.7.13
git 2.7.4
OS Information:
Kubuntu 16.04 64bit
KDE Plasma 5.5.5
Qt 5.5.1
Kernel 4.10.0-35-generic
All installed packages are up-to-date

### Additional Information
I have had a look with the debugging tools and recorded the JavaScript CPU Profile. There are exclamation marks whenever the function `_.intersection` from `~/.atom/packages/autocomplete-paths/node_modules/underscore/underscore.js` is called. I couldn't find out what it means, but maybe it helps.

Cheers,
Christian

Reproduce the issue in Atom on Kubuntu 16.04 by typing a path such as dir='/somedir/' in a file. Start with autocomplete-paths/node_modules/underscore/underscore.js and inspect calls to _.intersection, then confirm that path contents are suggested as expected.
