Fix bug regarding PS's change in displaying forme

In team preview, Gourgeist-N was displayed as just Gourgeist and a different
forme of it would be Gourgeist-* (to the best of my knowledge.) Now,
Gourgeist-N is also displayed as Gourgeist-*. This was causing a bug because
there is no pokedex entry for Gourgeist-*. Hopefully, this should fix the
problem by eliminating the -* from the name before searching for the pokemon
in the dex.
