Revert the UserOpenID model change which added the account_verified flag. The intention was to allow for the support of multiple UserOpenIDs for a given User, but in reality the solution wouldn't have provided this, because we have no idea which OP provided the e-mail address associated with the account. In the meantime, allow for the simple case of handling account_verified for a single UserOpenID, while not ruling out future support for the complex case.
