java.io.FileNotFoundException: /storage/sdcard0/PRIVATE/STG/SET.JSN

The STGUploader app causes my Sony rx100v to restart during app initialization. The camera goes black for a few seconds, then opens camera shutter.

I see the following in :\PRIVATE\STG\LOG:

[INFO] setting wifi enabled state to true
[INFO] Resume org.bostwickenator.googlephotos.LoginActivity
[INFO] Credentials obtained
[INFO] Pause org.bostwickenator.googlephotos.LoginActivity
[ERROR] java.io.FileNotFoundException: /storage/sdcard0/PRIVATE/STG/SET.JSN: open failed: ENOENT (No such file or directory)
[INFO] Resume org.bostwickenator.googlephotos.MainActivity

This might be related to #11, but I am not sure. I see that the SET.JSN is read in SettingsStore, but I am not sure why this file is not present on my sdcard. I could do a PR with a fix if I get a brief introduction
