Fix format assumption when resolving module dependencies (#10878)

* fix assumption when resolving dependencies

When resolving dependencies given a path, we are only interested
relative files from the current file. We are not interested in the
dependencies that are listed in your `package.json` and thus in your
`node_modules` folder.

We made the assumption that your imports have at least 3 characters.
This sort of makes sense because there will be a `.`, then the OS
separator like `/` and than a file name. E.g.: `./a` is the minimal
amount of characters.

This makes sense for `import` statements, but in the case of `require`,
it is totally valid to write `require('.')`. This will require the
current `index.{js,ts,mjs,cjs,...}` in the current directory.

Before this change, having a `require('.')` wouldn't crash, but the
dependency would not be marked as a module dependencies and therefore we
won't listen for file changes for that dependency.
