* Throw when attempting to save an unkown Send Type
I think it's best to only throw on unknown send types here.
I don't think we want to throw whenever we encounter one since that would
do bad things like lock up Sync if clients get out of date relative to
servers. Instead, keep the client from ruining saved data by complaining
last minute that it doesn't know what it's doing.
publish directly to internal test track to skip play store approval process for internal testers (artifact can then be manually promoted to alpha > beta > prod like before). This should bring the testing experience up to speed with TestFlight for iOS (i.e. push code > ci build > immediate availability)
