  "skipAutosaveOnLaunch": true, entry in settings.json results in crash on startup

hello,

then miRack crashes (like for instances by using the open or save entries of the file menu) it leaves the entry:
```
  "skipAutosaveOnLaunch": true,
```
in the settings.json file. as long as this line is in there, miRack will always crash again on startup. if i remove the line by hand, it will start up fine again.
