2 bugs with tvshows and local information

Hi,

I noticed 2 bugs when using local information and local artwork with tvshows.
Tested with latest nightly. (13.06.2013)

1. If I select Refresh from the information screen of a tv show, xbmc doesn't ask anymore if the local information (if present) should be used.

2. XBMC doesn't load the local seasonXX-poster.jpg if I add a new season to a exsiting tv show.
seasonXX-fanart.jpg gets loaded normally.
If I add a whole tv show with several seasons all seasonXX-poster.jpg's get loaded sucessfully.
When not using local information and artwork everthings seams to work fine.
