Remove duplicate promise resolve() calls in streaming JSON helpers

These two resolve calls should have resolved at roughly the same time, so it likely didn't affect the successful case. However, it could potentially supress errors returned by the `stream` promise if oboe reported "done" and `stream` encountered an error, the promise may have inappropriately resolved as complete and the promise rejection may have been swallowed.
