[sbossarte]

Description

Visiting https://example.com/0 causes Craft to render the template at index.html without any provided entry. This happens even if the homepage would normally use a different template.

Steps to reproduce

1. Start with a fresh Craft install
2. Set up a single to act as the homepage, using template _x.html
3. Set up another template at index.html as an example
4. Visiting the homepage https://example.com/ renders the single via _x.html
5. Visiting https://example.com/0 renders index.html

or

1. Start with a fresh Craft install
2. Set up a single to act as the homepage, using template index.html
3. Visiting the homepage https://example.com/ renders the single via index.html
4. Visiting https://example.com/0 renders index.html, but with entry undefined within the template
