New test round.

Create new Google Drive folder.
Sync tablet A to cloud folder: Initial upload, completes normally.
Apply several corrections.
Sync to cloud folder: Update server.
- file deletes are propagated to the server
- the other updates (merges) are not

Tablet B has an older copy of the library.
Sync tablet B to cloud folder: Update client. Do not search for new files.
Crash on NullPointerException comparing song XXX.
There was XXX.cho and XXX.jpg, and XXX.jpg was removed from the server.

EDIT: Some songs that were on tablet B and not on the server appeared on the server again, so the cloud folder was updated despite the "Update client" setting.
