Vite resolves paths to fs root instead of root in config

[joakimbeng]

⚠️ IMPORTANT ⚠️ Please check the following list before proceeding. If you ignore this issue template, your issue will be directly closed.

• Read the docs.
• Use Vite >=2.0. (1.x is no longer supported)
• If the issue is related to 1.x -> 2.0 upgrade, read the Migration Guide first.

Describe the bug

Browsing to a URL path that corresponds to an existing path relative to the file system root crashes Vite.
I.e. on a unix based file system going to http://localhost:3000/home tries to read the folder /home as a file, and going to http://localhost:3000/dev tries to read /dev as a file, instead of going to the index.html fallback.

This happens in v2.0.0 but not in v2.0.0-beta.70 or below.
