#68 Backup stats only filled after first file is uploaded

[Achim J. Latz]

The Backup progress stats (elapsed, remaining, total) are only filled with data after the first file was uploaded. During that initial upload, the fields are empty.

Depending on how big that first file is (i.e. how long that first upload takes), it can be confusing to the user to NOT see what is going on (especially since the progress bar is also not moving at that point during the first upload!)
