deleting a song that's queued to be scanned keeps the file handle open forever

I'm using an ntfs external hd for my library storage, and there's a `.fuse_hidden*` file that won't go away in a directory where i deleted a song that was planned to be scanned. I'm fairly certain the scan did not start before I deleted it.

```
$ lsof .fuse_hidden00003fc300000006
COMMAND PID USER FD TYPE DEVICE SIZE/OFF NODE NAME
node 2267 josh 80r REG 8,17 3172568 14986 .fuse_hidden00003fc300000006
