Update not repecting custom config for apps.vhost
I run an update for ISPC to the latest one (3.1.3) but notice that update is not respecting custom config for apps.vhost (in /usr/local/ispconfig/server/conf-custom/nginx_apps.vhost.master) as it is using the one that is downloaded / extracted (in /usr/local/ispconfig/server/conf/nginx_apps.vhost.master). As this custom apps.vhost only allow https access to all apps and via server hostname only, this caused failure to open app sites in the browser when they are not enabled due to the update is using the downloaded / extracted default nginx_apps.vhost.master instead of the customized one.
