jshint:files aborts with warning

[tejasbubane]

jshint:files task gives the following warning and aborts:

⇒  lineman build
Running "clean:dist" (clean) task
Cleaning generated...OK

Running "common" task

Running "coffee:compile" (coffee) task
File generated/js/app.coffee.js created.
File generated/js/spec.coffee.js created.
>> Destination (generated/js/spec-helpers.coffee.js) not written because compiled files were empty.

Running "jshint:files" (jshint) task
Warning: Path must be a string. Received null Use --force to continue.

Aborted due to warnings.

I think the issue was with grunt-contrib-jshint and was fixed, but since lineman uses v0.11.0 it does not have the fix. Upgrading should fix this.
