Fix "No tests were run"
Fix "No tests were run"

After including this packing in our ember app's package.json, was seeing:

```
1..0
# tests 0
# pass  0
# fail  0

# ok
No tests were run, please check whether any errors occurred in the page
```

Config in `ember-cli-build.js`:
```
sassLint: {
  disableTestGenerator: true
}
```

Setup:
```
ember -v
version: 1.13.8
Could not find watchman, falling back to NodeWatcher for file system events.
Visit http://www.ember-cli.com/user-guide/#watchman for more info.
node: 0.12.7
npm: 2.13.4
