Evolution cost for Purified / Trade discounted pokemon

[lramati]

(Moved fromxZise/14)

PokemonNameCorrector::getCandyNameEvolutionCostGuess tries to guess the current pokemon by matching the evolution cost that was read to the expected evolution cost for the species in the evolution line. However, purified pokemon cost less to evolve, which means these number won't line up and the function will fail, additionally, there are pokemon that when traded cost 0 candy to evolve, which also breaks this function
