[bug] [v2] IndexedDB path changed after upgrading to tauri 2

[hut36]

Describe the bug

After upgrading from tauri 1 to tauri 2, the IndexedDB directory changed from https_tauri.localhost_0.indexeddb.leveldb to http_tauri.localhost_0.indexeddb.leveldb. Since my app stores all data in IndexedDB, this will cause "data losing" from user's point of view.

This happens on Windows, the full paths are:

• C:\Users\[username]\AppData\Local\[appid]\EBWebView\Default\IndexedDB\https_tauri.localhost_0.indexeddb.leveldb
• C:\Users\[username]\AppData\Local\[appid]\EBWebView\Default\IndexedDB\http_tauri.localhost_0.indexeddb.leveldb

Reproduction

To verify that tauri 2 uses said IndexedDB directory http_tauri.localhost_0.indexeddb.leveldb, following these steps:

1. create a new app: pnpm create tauri-app
2. do anything that causes IndexedDB directory being created, for example, using idb: a. pnpm i idb b. open IndexedDB: openDB("test").then((db) => console.log("db opened: ", db));
3. build: pnpm tauri build --debug
4. run the app and check the directory

I've set up a repo at https://github.com/hut36/tauri2-indexeddb for you to test.

Expected behavior

The directory https_tauri.localhost_0.indexeddb.leveldb is expected, instead of http_tauri.localhost_0.indexeddb.leveldb. See above for the full path.
