fix: querying token factory from LCD

[emidev98]

Enable querying token factory with URL encoded token denom, that way LCD can be queried without failing due the following error:

{
  "code": 12,
  "message": "Not Implemented",
  "details": []
}

This will not cause issues because denoms aren't allowed to have % which will no create any collisions

LCD Query;
