Adding Anime mess up release group initial whitelist

[hergonoway]

Version : last master

When : while adding an Anime type show with whitelisted release groups.
What : while adding a show and selecting one or more release group into the whitelist everything looks fine. But after the show is created release group is not well set.

Example : if I add HorribleSubs during creation it appears as 12 release group one per letter like that : H,o,r,r,i,b,l,e,S,u,b,s. Which make medusa download all wrong group at first scan :)
