Work on #3879 though it doesn't fix it.
It does however fix the issue of weird behaviour and errors like
missing PID file: /var/run/ondemand-nginx/true/passenger.pid

being mapped here must be thelog.error
return value. So just returnnil
and compact. Users can still find the error messages in the system log.
