Options not passed to Bundler::Installer for bundling of "next" gem set

[zoso10]

In the after-install-all hook where we bundle a second time for the "next" gem spec set we don't pass the options argument to the #run method that was used in the first bundle. On first investigation it doesn't appear that there's any global state that holds the thor options object; this will make it tougher to pass into the hook block
