Remove all cruft from manually testing addons in fixtures

**what is the change?:**
We forked three of the fixtures into two variations to test two of the
react addons. We also added `console.log` statements to the addons to
verify that we were loading the right build.

This commit cleans it up by
- deleting forked fixtures
- re-adding the original fixtures
- removing `console.log` statements

**why make this change?:**
To get this branch ready for review.

**test plan:**
`cd fixtures && node ./build-all.js` and then check the updated fixtures
manually

**issue:**
#9765
