App crashing if local storage access is denied

[steffenkleinle]

Describe the Bug

We have sentry reports that the web app is crashing if access to the local storage is disabled:

Sentry Issue: INTEGREAT-APP-4Y5

Steps to Reproduce

1. Block integreat.app from accessing local storage/cookies as explained in the last section here
2. Go to https://integreat.app
3. See the app crash

Expected Behavior

The app crashes.

Actual Behavior

The app does not crash.

Additional Information

This might be due to anti tracking restrictions. Investigate if you can reproduce this.

I could reproduce this on firefox (desktop) by explicitly adding integreat.app as blocked as defined here in the last section: https://support.mozilla.org/en-US/kb/storage

I linked the wrong issue in #2975, reopening.
