🐛 BUG: Circular dependency fix broke starting up with some packages

Quick checklist

• I am using the latest version of Snowpack and all plugins.

What package manager are you using?

npm

What operating system are you using?

macOS

Describe the bug

The PR https://github.com/snowpackjs/snowpack/pull/3562 seems to have caused some issues with both the package Nivo it was trying to fix, as well as others.

A lot of errors similar to this pop up:

[14:28:42] [snowpack] Error: ENOENT: no such file or directory, open 'dir/node_modules/.cache/snowpack/build/lodash@4.17.21/lodash/get.js'
[14:28:42] [snowpack] [500] /_snowpack/pkg/lodash.get.v4.17.21.js
[14:28:42] [snowpack] [Error: ENOENT: no such file or directory, open 'dir/node_modules/.cache/snowpack/build/lodash@4.17.21/lodash/set.js'] {
  errno: -2,
  code: 'ENOENT',
  syscall: 'open',
  path: 'dir/node_modules/.cache/snowpack/build/lodash@4.17.21/lodash/set.js'
}

As well as a lot of these:

[14:27:29] [snowpack] lodash/isDate: Unscannable package import found.
Snowpack scans source files for package imports at startup, and on every change.
But, sometimes an import gets added during the build process, invisible to our file scanner.
We'll prepare this package for you now, but should add "lodash/isDate" to "knownEntrypoints"
in your config file so that this gets prepared with the rest of your imports during startup.

though I only included lodash in this list, the same sort of errors come up from other packages.

I believe it has something to do with having two packages that require two different versions of another package but I’m not entirely sure.

Steps to reproduce

1. npx create-snowpack-app my-app --template @snowpack/app-template-react-typescript
2. npm i @nivo/core @nivo/bar
3. Replace App.tsx with

import { ResponsiveBar } from '@nivo/bar';
import React from 'react';
import './App.css';

It seems to break in the first rc for 3.8.7 which was accidentally named snowpack-3.8.6-rc.0 and then republished as snowpack-3.8.7-rc.0, and subsequently published as 3.8.7 without any changes since snowpack-3.8.6-rc.0. This was a fix by @drwpow for a circular dependency loop issue but seems to have broken some other stuff.

I did a quick scan on the changes between 3.8.6 and 3.8.7. I have a hunch that the issue is caused by something in snowpack/src/sources/local.ts, probably something with the memoization stuff.

There are also some changes in the init command, but this is just a package.json exists check.

Can anyone confirm that 3.8.6 works for them?
