• If your PR isn't addressing a small fix (like a typo), it references an issue where it is discussed ahead of time and assigned to you. In many cases, features are absent for a reason.
• Prefix your PR title with feat:, fix:, chore:, or docs:.
• This message body should clearly illustrate what problems it solves.
• Format & lint the code with pnpm format and pnpm lint

Fixes #914, which fixes #844.

Fix incorrect falsy value when checking if there are components to remove at the end of the update process.

Also, fix the init script, which incorrectly creates a utils.js.ts file. The file extension is already added upon creation, so we don't need this. We might however need the file extension within the config file or a better alias resolution mechanism, so maybe I should move that out of this PR? Or maybe it's a good first fix for the file creation?
