fix: disable custom querier

[loloicci]

Description

This PR closes the custom querier for other modules.

closes: #115

Motivation and context

Since Finschia/finschia-sdk@0f4ad5b, custom query is opened for our token/collection module.
It is not as expected this is still alive after we separate x/wasm and x/wasmplus.
So this PR deletes it.

Alternative queries for our original modules are going to be opened with the stargate query feature in later versions.

How has this been tested?

After merging, the default custom querier is the same as upstream.
