bug: when last-visited-community cookie points to non-existent community, infinite redirect loop on login happens

[tefkah]

What went wrong, step-by-step?

1. Create new community
2. Go to said community
3. Somehow delete/rename community (usually happens on pnpm -F core reset)
4. Login again
5. Get thrown in infinite redirect loop

What did you expect to happen?

What URL can we use to see the issue?

What browser/operating system were you using?
