verifierGetProofSchemas doesn't filter

[joevolleyball]

If I have an agent that has registered multiple proof schemas and then try to query just one, I end up getting the full list of the agent's proof schemas.

const schema = await agent.verifierGetProofSchemas({name: "first_and_last_name_proof"});

Looks like the filter built up in the query object isn't passed in on the http request at https://github.com/IBM-Blockchain-Identity/openssi-websdk/blob/master/nodejs/sdk.js#L776
