Remove not-very-useful caching for homepage modeling

Huh, I hadn't realized that like, we'd already set up the controller to
always *run* basically all of the modeling logic, and the caching in
the view layer wasn't saving us any queries anymore. Kinda silly!

Remove the caching call, just to simplify the codebase (I like to avoid
caching things that don't specifically need it!).

And hey, love that the modeling code in the controller is now *way*
faster to run! You love to see it!
