Drive letter for image filename from database on Windows

[Maik Qualmann]

We use the KF5:Solid framework to get the drive information. The UUID is the 
partition UUID. So we are looking for the UUID that the Solid Framework 
returns to us as drive information and we get the corresponding path. 
Therefore, the drive letter can change with removable drives, we would find the 
new one via the UUID.
