core.portmanager: Fix race condition in initialization of SNI cert map Under some circumstances when hosts and modules are loaded in some certain order, entries end up missing from the SNI map. This manifests in e.g. `curl https://localhost:5281/` giving an error about "unrecognized name". The `service` argument is `nil` when invoked from the "host-activated" event, leading it to iterating over every service. And then it would not be fetching e.g. `http_host` from the config, which explains why https would sometimes not work due to the missing name entry. Because when `service` is included, this limits the iteration to matching entries, while also returning the same value as the `name` loop variable. Because `name == service when service != nil` we can use name instead in the body of the loop.
