AppID invalid exception on clean startup

Problem is not on startup, but after loading a freshly saved file.
The startup issue was caused by a debug parameter always loading a local test file

Update: Files do not get saved correctly.
The internal DB is correct, but no content is written to the DB file

Backup throws no exceptions, doing a commit right before backup does not help either.
Overwriting a working save file with an "empty one" does not overwrite at all. The previous working file remains

Updating SQLite version exposes an error during saving.
See xerial/sqlite-jdbc#818

Saving before adding the title of a song in a playlist does not cause issues; Adding one does.
This is not repeatable when doing other actions such as archiving multiple songs

[witmoca]

Current method to reproduce (with :

Create new file
Add one playlist
Add artist name
Add one song title
Safe file

File now saved (if saved at all) does not contain the database

Bug also present in version 1.2.0, so not a result of recent DEV
