Concurrent bower install error.

[raphaelquati]

We have a Jenkins server running a multibranch job. When a release is finished in the repo (gitflow), develop and master branches are updated. The multibranch job is triggered, starting building develop and master branches at same time.

The build job execute grunt that call "bower install". One branch runs ok, the other stops with an error.

I know the problem is not with bower directly. The problem is in configstore (2.0.0) which uses write-file-atomic
