When update ISPConfig, if a custom port is set for the apps vhost domain, then it returns to the default 8081, only on the config file (remains custom on the web panel)

Since first time I noticed this problem nobody fixed it, so I decided to do. When you update ISPConfig and have a custom port for apps domain, after any ISPConfig update apps.conf returns on the default value of 8081 even if on the Web Panel the port is stored correctly. Until now, to fix it, the user had to modify the port on the Web Panel with a temporary one, then modify it back to what it was before the update. Studying the code I figured out that this is a nginx only bug.

In my opinion it's pretty important to fix this issue because if the user is running ISPConfig under Cloudflare, this doesn't allow to use the default 8081 port so you have to change it to a non default value.

This was the issue report: #5932 (closed)
