berkshelf shares the wrong folder when bringing up new vagrant box

[ccope]

Steps to repro:
vagrant destroy && vagrant box remove (your box name)
vagrant up --provision

Chef run will fail due to missing cookbooks (like apt)

This only occurs when the box is added. I see on the first run it vendors the cookbooks into a shelf (in (~/.berkshelf/vagrant-berkshelf/shelves/...), but then it tries sharing the main project 'cookbooks' folder (next to my Vagrantfile) rather than the shelf. vagrant reload && vagrant provision will correctly mount the shelf instead.

Vagrant 1.7.4, 1.8.1
ChefDK 0.8.0, 0.10.0
