Iterable.updateSubscriptions fails silently

[p-sebastian]

Calling Iterable.updateSubscriptions during app init after initializing Iterable

Iterable.initialize(apiKey, config);
// new userId that creates a new user
Iterable.setUserId(anonymousId);

can fail silently if done too quick in succession, XCode will only log:

.9520:0x280d29500:RequestProcessorUtil:sendRequest(requestProvider:successHandler:failureHandler:authManager:requestIdentifier:):32: No user exists with userId

13:26:56.9530:0x280d29500:RequestProcessorUtil:defaultOnFailure(_:):112: updateSubscriptions failed:, No user exists with userId

even calling await Iterable.getUserId() will return the userId but the call will fail still.
but the function itself is not a Promise that returns any value indicating if it succeeded or not. meaning there is no way to know if we should try again in a different session or not.

Ideally Iterable.updateSubscriptions should be a promise that returns it's status.
