- When we have multiple wrapped input consumers, mConsumer will be set to the wrapper while the caller can actually be the input consumer being delegated to (ie. other activity ic). So we should clear the consumer state if the caller is anywhere in the IC hierarchy. This results in a separate issue where mGesture could be cleared during onConsumerAboutToBeSwitched() before being passed to the new consumer, so make a copy of the previous state just for passing to the new consumer.
