J. Ryan Stinnett 328f0cd6bf Notify user when crypto data is missing
If we have account data in local storage but nothing in the crypto store, it
generally means the browser has evicted IndexedDB out from under us. This adds a
modal to explain the situation and offer to completely clear storage to get
things back to normal.
