Fix warm-cache groups runtime error

Running warm-cache groups would cause the following runtime exception:

```
[2023-03-09 17:53:54,398] [SSH warm-cache groups  (admin)] ERROR
com.google.gerrit.sshd.BaseCommand : Internal server error (user admin
account 1000000) during warm-cache groups
groovy.lang.MissingMethodException: No signature of method:
com.google.gerrit.server.account.GroupIncludeCacheImpl.subgroupsOf() is
applicable for argument types:
(com.google.gerrit.reviewdb.client.AccountGroup$UUID) values:
```

The subgroupsOf method is no longer available, also the cache.get()
returns an optional rather than null.
