[Bug]: Infinite load after update with no console errors

@dbrans is already working on this.

Since Apr 3, 2025.

### Describe the bug

We are receiving reports of an infinite loading screen after updating to v12.15.0. In one report, the error was encountered after updating from v12.13, and there were no console errors that seemed relevant (we checked the UI, service worker, and offscreen document consoles).

The problem was resolved by disabling and re-enabling the extension.

### Expected behavior

_No response_

### Screenshots/Recordings

_No response_

### Steps to reproduce

We don't yet have reliably reproduction steps. In the one confirmed case, it was encountered after force-updating from v12.13.0 to v12.15.0.

I was able to reproduce this once locally by doing an update test from v12.12.0 to v12.15.1. The steps I followed were as follows:
* Create an empty directory for the test
* Copy the files from a v12.12.0 build into the directory
* Load this directory as an unpacked extension in Chrome
* Proceed through onboarding (import or new wallet, doesn't matter) and wait a few seconds on the home screen (to ensure there is enough time for the vault to persist).
* Disable the extension
* Delete all files in the directory
* Copy the files from a v12.15.1 build into the directory
* Enable the extension and quickly reload it (immediately after enabling)
* Open the browser-action popup

At that point I saw the infinite load. But then after reloading the extension again, the problem disappeared.
