title: Reset Firebase cache
body: <p>While developing with Firebase, I manually added a data record in the console but forgot one entry, which caused the app to crash. I've corrected the problem in the console but, because I was using Firebase's data persistence, the original data error persists, causing the crash again.  If I switch the persistence off, everything is fine but the cached store isn't being updated.  Has anyone had this problem and found a way to solve it?</p>
