[bug] Failed to rename app, directory not empty

[Guilherme-Vasconcelos]

Describe the bug

I have just created a brand new tauri project using create-tauri-app. Then I ran npm install, followed by npm run tauri dev and got this panic:

> npm run tauri dev

> my-tauri-app@0.0.0 tauri
> tauri "dev"

     Running BeforeDevCommand (`npm run dev`)

> my-tauri-app@0.0.0 dev
> vite

  VITE v5.0.12  ready in 431 ms

Caused by:
    Directory not empty (os error 39)
note: run with `RUST_BACKTRACE=1` environment variable to display a backtrace

Despite the panic, I can open http://localhost:1420/ in my browser and it displays the default tauri page, so I'm not really sure what effect the panic had but it doesn't seem to have affected the startup:

Reproduction

Run the following commands:

1. mkdir my-tauri-app
2. cd my-tauri-app
3. npm create tauri-app@latest . --template svelte-ts --manager npm

In the create-tauri-app interface, pick the following:

1. Package name: my-tauri-app
2. Choose which language to use for your frontend: TypeScript / JavaScript - (pnpm, yarn, npm, bun)
3. Choose your package manager: npm
4. Choose your UI template: Svelte
5. Choose your UI flavor: TypeScript

Wait for the project to be generated, then run the following commands:

1. npm install
2. npm run tauri dev

You should see the panic I mentioned in the description field.

Expected behavior

I expected the default generated project to run without panics.

It seems like I figured out the issue: because I used npm create tauri-app@latest . (to initialize the project in the current directory, which should be allowed according to create-tauri-app's README), my package.productName in src-tauri/tauri.conf.json was set to ".". I changed it to "my-tauri-app" and now it works.

Why is this issue closed if nothing was done to address the problem? Users expect running create-tauri-app with the current directory passed should either set the app name to the current directory or prompt for an app name
