Downloads missing from list despite of being downloaded

[vi]

I add a torrent to Tribler, it starts downloading it. I go to "Downloads" page, but see no entry in the list for the new torrent. If I add it again, it shows "this torrent is already being downloaded".

Total downloads counter on the "Downloads" tab header is showing the visible downloads instead of actual downloads...

This may be connected with space outage for collected_torrent_files. After find ~tribler/TriblerDownloads/collected_torrent_files/ '(' -iname '*.jpg' -or -iname '*.png' ')' -delete downloads began to appear in the list again (and No space left on device ceased to appear in console again and again).

Does Triber correctly prioritize collected_torrent_files in case of limited storage space?

Restarting Tribler after trimming pictures from collected_torrent_files made it to "remember" the lost downloads.

When #1175 gets merged, this one can be closed too as the torrent store will be on the statedir.

I will open a separate issue to work on the whole disk space checking thing.
