Deluge does not truncate files when it should

[Nick Koretsky]

Its actually two bugs, but they are related

1. There is 2 files, B is larger than A, but its content is identical to A up to A size. If torrent is created using A, and then added to deluge pointing to B followed by force recheck, deluge will accept it as 100% complete, but will not truncate the file to A size. So now you have a file that has junk at the end, but deluge is happy with it and claims that everything is ok.

2. This is how you actually end up with the files from first bug. You add a torrent with "Move Complete" location selected. But you didnt check that there is folder here with an exact same folder and file names as in a torrent you have just added. Deluge downloads new torrent, and in the move phase, it copies content of a new files into older ones, but doesnt truncate larger files.

P.S. This is on deluge 2.2.0 with libtorrent 2.0.8.0, i am not sure if this bug is related to deluge core itself or libtorrent
