Fix dexsearch giving all pokemon for any move combination

Zarel's fix caused dexsearch to give every mon as a result for a move search

[11:22:24] <%Arcticblast> %Kiba Roserade: !dexsearch Boomburst
[11:22:24] <%Arcticblast> Shelgon, Zygarde, Venusaur, Venusaur-Mega, Charmander, Charmeleon, Yveltal, Charizard-Mega-X, Xerneas, Squirtle, and 791 more. Redo the search with "all" as a search parameter to show all results.
