fix: thumbnail leak when removing the last file (#423) 

bf6c062 tried to fixed the thumbnail leak, but it was done inside a
`if (n+1 < filecnt)` branch, meaning the thumbnail was still leaking
away whenever the last file was removed.

we need to unload the thumb regardless of whether it's in the middle or
not. this bug was caught due to the recent `assert`s that were added in
01f3cf2.
