If card already (un)frozen, ask user if they want to toggle its state #18
Description
Currently Alexa sometimes gets confused between the two intents for UnfreezeCard/FreezeCard - so users may trigger one, while actually wanting the other. To minimize the annoyance of this, Alexa should ask if they want to toggle the state, rather than just bailing out.
- This would require setting up state on the Amazon.YesIntent and Amazon.NoIntent, so we know which handler to use immediately after a user has triggered FreezeCard/UnfreezeCard
