Remove override for outdated views

I'm not sure if anyone else is running into this, but I was unable to precompile my deface views without removing this override.

Looks like it was last seen in [6efd86d2](https://github.com/spree/spree/commit/6efd86d24f3094966afa14ee07b87d715eadff2a) on spree/spree.
