Removed redundant code and fixed incorrect ImageType

- Removed code from first AniDB_Anime.GenerateContract which repeats
  work that is done earlier in the method (ie. the image info is retrieved
  on line 1987-1994, and they're converted to contracts in the GenerateContract
  call on line 1997).
- Fixed the contract generation for TvDB Banners in second
  AniDB_Anime.GenerateContract method. It was using JMMImageType.TvDB_FanArt,
  and should have been JMMImageType.TvDB_Banner.
