Invalidating more stuff

I'm still going through all the tests looking for errors. Most of them are fine and I don't think it's worth reporting any spelling or grammatical mistakes unless it makes it harder to understand the test.

• I invalidated test 6 because a button was located on a wrong page
• Test 8 also had an incorrect button name

Also, here's a link to the LibriFox logo with a solid color, I think blue is good but maybe a different shade would be better. Either way the fox looks really good.
