Title: This fixes #2532773 (duplicate CSS loaded on refetch)

When refetching module, the logic for checking if a CSS module was being bypassed. Instead of running through all the logic again, I'm short cutting it here for performance.

This checks the modules for new CSS (JS not mattered here because of `YUI.add` registration), then it checks to see if it's available with `isCSSLoaded`, then if it's already there, it removes the items and calculates again.
