Autoselect a single drive by using DriveScanner scan event

Browse Source 
- The autoselection only happens once the user has selected an image to
prevent weird behaviour.

- The autoselection happens only if the current selected drive is
different from the new drive in order to avoid selecting the same driver
over and over again if it still is the only one.
