SFTP get completely disabled in certain setups when enableling it (hestiacp#4859)

* When set to Subsystem       sftp    /usr/lib/openssh/sftp-server

For some reason it changes to #Subsystem       sftp and doesn't work when sftp is enabled

 subsystem request for sftp by user eris failed, subsystem not found

* Check if this works better
