Auto loading stats on launch does not work

Reported by UlyssesZh on GitHub

Auto loading stats on launch does not work. I can, however, load stats manually after it launches.

Relevant part of the config file:

statsSaving:
  autoSave: true
  autoDestination: /home/ulysses/data/KeysPerSecond/stats
  autoFormat: 'md.kpsstats'
  autoInterval: 1000
  saveOnExit: true
  loadOnLaunch: true
  saveFile: /home/ulysses/data/KeysPerSecond/stats/md.kpsstats

Tested on Linux with KPS 8.8.
