Exports + Client: Refactor registering a client

- Make sure the global exports state is only set on successful
creating
- Only call discovery when adding a server to ensure we get the most
up to date args. Creating a client should have no network calls. Fixes #12
- Split creating a client in New and Register in the GO api
