hs-v3: Always generate the descriptor cookie
It won't be used if there are no authorized client configured. We do that so
we can easily support the addition of a client with a HUP signal which allow
us to avoid more complex code path to generate that cookie if we have at least
one client auth and we had none before.
Fixes #27995

+ o Minor bugfixes (hidden service v3, client authorization):
+ - Fix an assert() when adding a client authorization for the first time
+ and then sending a HUP signal to the service. Before that, tor would
