Associate oauth client with existing account - error

[vindberg]

• First having registered a user using Google, giving the name "Anders".
• Then adding a password, and removing the Google association.
• Then logging out.
• Then using Google to login.
• On the associate with user page I then write "Anders".
• Going to the /Manage page now returns an error in \Raven.Contrib.AspNet.Auth\AuthProvider.cs:

Sequence contains more than one element

Line 278:            using (var db = _store.OpenSession())
Line 279:            {
Line 280:                var user = db.Query<Account>()
Line 281:                             .Customize(q => q.WaitForNonStaleResultsAsOfLastWrite())
Line 282:                             .SingleOrDefault(a => a.UserName == userName);

Suggested solution:

In the AuthProvider add:

        public void CreateExternalAccount(string userName, string identifier, string providerName)
        {
...
                var queryExistingUser = db.Query<Account>()
                              .Customize(q => q.WaitForNonStaleResultsAsOfLastWrite())
                              .Where(a => a.UserName == userName);

                if (queryExistingUser.Any())
                    throw new DuplicateUserNameException(userName);

...

And then add appropriate try catch in the ExternalLoginConfirmation action in AccountController. :+1:

Hi!

Thanks for the report!

Unfortunately I've been extremely busy the last couple of months and haven't been able to do any work on the auth providers. I'd love a pull request, that would be great.
