If I switch theme, the old theme assets still seem to be retained on publish

[canstudios-nicolaw]

Expected Behaviour

If I switch course theme then the theme assets for the current theme should be included in publish.

Actual Behaviour

I have a theme that contains a lot of assets. If I create a course with Vanilla and publish it then the size of the publish is 645kB. If I then switch to my big theme and publish the download is 8.7MB.

If I then switch back to vanilla and publish the download remains at 8.7MB. It's like it hasn't cleared the assets from my theme.

Steps to Reproduce

1. Create basic course with vanilla
2. Publish and note download size
3. Switch to a theme which uses lots of assets
4. Publish and note increased download size
5. Switch back to vanilla
6. Publish and note download size hasn't decreased
