So I think updating the mailbox name to NFC should also update any
matching subscriptions of the user. Otherwise, the subscription gets
lost and we get constant errors in the logs.

I thought this was already fixed, but looks like accidentally the test was using mailbox_list_utf8=yes. With the default =no it was broken. Attached a fix.

I guess nobody looked at the accidentally wrong diff :) But the fix is now committed: https://github.com/dovecot/core/commit/7b9cdf4848655d423bea78f5dbba7803350a2...
