/api/delegates/{id}/blocks endpoint does not honour query params

[alessiodf]

https://api.ark.io/api/delegates/alessio/blocks?height=21154000 does not honour the height query parameter and lists all results without any filtering. The same applies for any valid criteria parameter, even though the schema allows it which implies it should work, since for example, https://api.ark.io/api/delegates/alessio/blocks?heights=21154000 is rejected for failing schema.
