Noticed that we're checking more module paths than necessary. In
particular the module path array contains a couple of entries with a
duplicated `node_modules/node_modules` suffix.
```js
[
// ... more entries before here, where some also contain duplicate suffixes
"/Users/marvinhagemeister/dev/preact-render-to-string/node_modules/.deno/node_modules",
"/Users/marvinhagemeister/dev/preact-render-to-string/node_modules/node_modules", // <-- duplicate suffix
"/Users/marvinhagemeister/dev/preact-render-to-string/node_modules",
"/Users/marvinhagemeister/dev/node_modules",
"/Users/marvinhagemeister/node_modules",
"/Users/node_modules",
"/node_modules",
"/node_modules" // <-- duplicate entry
]
```
This was caused by a misunderstanding in how Rust's
[`Path::ends_with()`](https://doc.rust-lang.org/std/path/struct.Path.html#method.ends_with)
works. It's designed to match on whole path segments and the suffix
`/node_modules` is not that, except for the root entry. This meant that
our check for if the path already ended with `node_module` always
returned `false`. Removing the leading slash fixes that.
While we're at it, we can remove the last condition where we explicitly
added the root `/node_modules` entry since the while loop prior to that
takes care of it already.
