Scanning Medialibrary : Resume scan not always working

Description

With a very long scan not achieved, in my case with a network share and a huge collection of medias on it, when you re-open VLC, already scanned medias are not displayed.

Sometimes, it looks like the medialibrary scan is restarted.
