Correct ClientReady hook in Auto Poll mode

[adams85]

Describe the purpose of your pull request

So far the ClientReady event has fired in Auto Poll mode only when receiving 200, 304, 403 or 404 status code. In other cases (including the case of network errors) maxInitWaitTime has been waited before firing ClientReady.

Breaking changes:

• Change the behavior of the ClientReady hook to fire after the completion of the first fetch operation in Auto Poll mode - regardless of success or failure - to make the behavior consistent with other SDKs.
