Prerequisites:
A. You have a rule for a TV show that has season = 1, episode =1
B. You have a recording of that show with season = 0, episode = 0
C. You don't have a row in recordedartwork for this show, season 1
D. This show has > 1 fan art in ttvdb.com
E. You run "mythmetadatalookup --refresh-all-artwork"

Steps in issue:
1. The rule will run first and create a row in recorded artwork with the valid fan art for season 1
2. The recording will also run since there's no row in the db with season = 0
3. During the metadata lookup the recording will hit "handleRecordingGeneric" method which will call something like: "ttvdb.py -l en -M <show name>" which will return results with no fan art. However, it will also set the season to be 1
4. This will overwrite the original row for season 1 with no fan art.
