[Bug] Can`t use same versions of aliased packages with peer dependencies

[ImBrek]

• I'd be willing to implement a fix

Describe the bug

• I have package.json like this, and it works

"dependencies": {
    "lib1": "npm:lodash@^4.17.15",
    "lib2": "npm:lodash@^4.17.15"
  }

• But, if i trying this, it doesn`t work

  "dependencies": {
    "lib1": "npm:@testing-library/react@10.0.4",
    "lib2": "npm:@testing-library/react@10.0.4"
  }

$ yarn

• And finally, it works

  "dependencies": {
    "lib1": "npm:@testing-library/react@10.0.4",
    "lib2": "npm:@testing-library/react@10.0.3"
  }

Repro

const installPromise = packageJsonAndInstall({
  dependencies: {
    "lib1": "npm:@testing-library/react@10.0.4",
    "lib2": "npm:@testing-library/react@10.0.4"
  }
});

await expect(installPromise)
  .resolves.toBeTruthy();

Environment if relevant (please complete the following information):

• OS: [OSX]
• Node version [13.5.0]
• Yarn version [2.0.0-rc.33]

Not to argue if this is a bug or not, but just out of curiosity...
But I'm wondering in what use case you would have two different aliases to the exact same version of another package in the your own package?

[ImBrek]

It is just part of release cycle. I want to have a bundle with two versions on package, stable and current and switch between them in runtime.

For example, during development i have something like this

  "dependencies": {
    "calc-stable": "npm:@private/calc@2.0.0",
    "calc": "npm:@private/calc@2.0.6"
  }

when release comes, I want to change version of stable package

  "dependencies": {
    "calc-stable": "npm:@private/calc@2.0.6",
    "calc": "npm:@private/calc@2.0.6"
  }

I've managed to isolate this to packages with peer dependencies. It works to alias the same version of lodash multiple times because it doesn't have any peer dependencies, unlike @testing-library/react. It looks like the virtual package created for @testing-library/react gets lost when it's aliased multiple times, I'll investigate.
