stargate queries not serialized correctly

[wesl-ee]

Enabling the stargate feature flag will query the x/oracle and x/marketmap modules via Stargate QueryRequest::Stargate instead of by custom message type QueryRequest::Custom. The correct path is provided but the data needed for the query is not serialized correctly and results in Error: rpc error: code = Unknown desc = Generic error: Querier contract error: codespace: undefined, code: 1: query wasm contract failed: unknown request.

Stargate is a deprecated way to make queries from the wasm module, and worth noting that neutron_sdk removed stargate from their exported bindings. We will either fix the stargate feature flag or remove it in the future.
