store: Handle invalid API key on register-queue
The method loadPerAccount has two call sites, i.e. places where we send register-queue requests: 1. _reloadPerAccount through [UpdateMachine._handlePollError] (e.g.: expired event queue) 2. perAccount through [PerAccountStoreWidget] (e.g.: loading for the first time) Both sites already expect [AccountNotFoundException] by assuming that the `loadPerAccount` fail is irrecoverable and is handled elsewhere. This partly addresses #890 by handling authentication errors for register-queue. Fixes: #737 Signed-off-by: Zixuan James Li <[email protected]>
