Increments cache key for modules page
Increments cache key for modules page

Instructors were getting a cached copy of the modules page, but
a new copy of context_modules.js.  The new version of context_modules
requires an id to be present as an element on the page.  The cached
copies of this page does not include an id attribute.

The problem resolves itself anytime the cache is busted by modifying
other aspects of the module.  This forces the cache to bust for
everyone so they get a new copy of the page.

fixes CNVS-22413

Test Plan:
  - Load up an old course (you need to have an old cached copy of the page)
  - You should be able to add an item to a module without problems.
