Desktop client deletes synchronized files if it finds FAMT is down

If the FAMT daemon on the Filr server crashes or becomes offline, the REST server may indicate to the Desktop client that Net Folders no longer exist which in turn causes the Desktop client to delete all previously synchronized (or offline) files.

The following error was observed in the filr.log file:

2016-05-16 21:29:48,944 [filesync-monitor] [WARNING] Exception: <class 'aca.excepts.InternalServerError'> (aca.excepts)
