ConcurrencyException

[veild]

Hey, I can still trigger this Exception, which you have fixed in WPF#44:
Relational.ClientDataStoreDbContext'. Microsoft.EntityFrameworkCore.DbUpdateConcurrencyException: Database operation expected to affect 1 row(s) but actually affected 0 row(s). Data may have been modified or deleted since entities were loaded. See http://go.microsoft.com/fwlink/?LinkId=527962

It occurs if you open up the SettingsControl and log out during the data-fetching from the server. If you are fast enough you can trigger the exception in the ClearAllLoginCredentialsAsync() method or at least in the SaveLoginCredentialsAsync().
