__home__ returns 200 instead of 404

[ccchapman]

Steps to reproduce:

1. Disable Blitz
2. Have section with uriFormat: '{slug}'
3. Create entry in section with slug of __home__
4. Expect curl -I https://mysite.com to show 200 status code
5. Expect curl -I https://mysite.com/__home__ to show 404 status code
6. Enable Blitz
7. Load https://mysite.com (to warm cache)

Actual behaviour:

curl -I https://mysite.com/__home__ shows 200 status code (returning web/cache/blitz/mysite.com/index.html)

Expected behaviour:

curl -I https://mysite.com/__home__ shows 404 status code
