Use closeReason provided in didCloseWithCode delegate for the NSURLSessionWebSocket code path

Use closeReason provided in didCloseWithCode delegate.

Currently we're looking at the task's closeReason (which is not wrong), but making sure that we use the close code and reason provided in the delegate callback to ensure there is no weird bug that we hit in the future

ASSERT([reason isEqualToData:task.closeReason]);
That'll catch these future bugs you mentioned.
