Fix modules formatting on course home page

The styling for modules on the home page was broken, so we fixed it by
ensuring that the css for modules is now included where/when the context
module page is loaded.

Test Plan:
1. Go to your course home page.
2. Make sure your course home page settings are set to show modules
by default
3. Observe that your modules are styled correctly with css.
