Description ember install fails on first attempt, succeeds on second.

Steps to Reproduce

$ ember new --no-welcome --yarn test-app
$ cd test-app
$ ember install ember-composable-helpers

🚧
Yarn: Installed ember-composable-helpers
Install failed. Could not find addon with name: ember-composable-helper

This happens on every Ember add-on tested, including ember-cli-typescript, ember-cli-mirage, ember-cli-string-helpers, ember-composable-helpers, and ember-uuid.

@nadnoslen Should be fixed by https://github.com/ember-cli/ember-cli/pull/10014.

So I’m seeing this as an issue when running ember install for any addon that has a default blueprint (a blueprint with the same name as the addon). For example when you run ember install empress-blog it throws an error

Install failed. Could not find addon with name: empress-blog

I have done a git bisect and I have confirmed that it is indeed https://github.com/ember-cli/ember-cli/pull/9487 that caused the issue, specifically this commit: https://github.com/ember-cli/ember-cli/pull/9487/commits/22b799b51410546d8e07685c9b621da8c11998d7

Unfortunately this is a massive PR and I’m wondering if we can actually just revert it while we figure out what went wrong? I don’t even know how to test this to make sure that it doesn’t break 🙈
