* [Go][Client] Ensure test errors don't crash
Previously we did not interrupt execution of a test case
when an error was returned from an API call. This was
causing the tests to crash as soon as we try to
dereference the response.
We now fail the tests as soon as the first API error
is received.
* [Go][Client] Use configured Scheme and Host in requests
Previously we were simply setting the Host header and
completely ignoring the configured scheme.
