core.portmanager: Restore use of per-host 'ssl' for SNI hosts. Fixes #1915. This was an unintentional regression, as per-host 'ssl' options became valid in 0.12 when SNI support was added for direct TLS ports. While we encourage most people to use the simpler automatic certificate selection (and it seems most do, given the overlooking of this bug), there are likely always going to be use cases for manually-configured certificates. The issue was introduced in commit 7e9ebdc75ce4 which inadvertently removed the per-host option checking for SNI.
