Fixed result content for Season Pack results

Was having issues with Season packs the last few days, I saw you were doing a little tidy up in recent commits (Labelled "Possible fix For Failed to Send Torrents") and it meant that the content data for a result object to be downloaded was no longer being retreived for season packs. Confirmed this with a bit of logging (and some digging on the deluge web server):

```
2014-08-23 19:07:13 DEBUG    SEARCHQUEUE-BACKLOG-78817 :: Calling Deluge Client
2014-08-23 19:07:13 ERROR    SEARCHQUEUE-BACKLOG-78817 :: Deluge: Failed Sending Torrent 
2014-08-23 19:07:13 DEBUG    SEARCHQUEUE-BACKLOG-78817 :: Deluge: Exception raised when sending torrent: must be string or buffer, not None
```

Looks like others were having problems too:

Hope it helps and that I've followed the guidelines here (first-time contributer!) :-)
