fetching file information does not return 100% completion

tl ; dr https://github.com/tribler/tribler/issues/3499

Call to file_progress to fetch file information does not return 100% completion, even though the file is there.

what should happen:

when you have a file that is 100% there, file_progress should return 100% for that file.

what happens:
it does not return 100% for some complete files, see example in above link.

libtorrent-rasterbar: 1.1.1-1build2 / 1.1.5-1build1
ubuntu: 17.10 artful / 18.04 bionic

both tribler ( both 7.0.1 and next + 0f36719 ) and apparently qbittorrent (see above issue) do not report accurate values for whether or not a file within a torrent(see above issue) is complete.
