Remove vagrant-wrapper

The vagrant-wrapper gem is not actually required for anything; if installed, it monkey patches Object and causes bundler to behave in strange ways, including saying that it is required when it is not. I recommend removing it from all Gemfiles and uninstalling it from your system.

We jokingly call it a virus of the rubygem world, spreading by means of pull requests :)
