alias domain produce a none.domain

[cchris-org]

Set an Alias to a Domain and select "none" on auto subdomain.
It will generate a none.aliasDomain.xx wich could not verify by letsencrypt

my solution in apache2_plugin.inc work for me.

if(isset($aliasdomain['subdomain']) && ! empty($aliasdomain['subdomain'])) {
// .. we dont like "none.aliasdomain"
if($aliasdomain['subdomain'] != "none"){
$temp_domains[] = $aliasdomain['subdomain'] . "." . $aliasdomain['domain'];
}
}

same solution also works for editing the nginx_plugin.inc
