OneDrive backup at shutdown fails.

[wvdvegt]

The Button Tools|Options|Cloud Storage Service 'Update settings file' works as it should. So credentials etc are ok.

However when you check the checkbox 'Always upload befre EVEMon closes' Evemon hangs at shutdown displaying a statusbar message it's trying to upload to OneDrive.

The two share the same call to OneDriveCloudStorageServiceProvider.csUploadFileAsync(). In one case it works, for the other it fails.
