[gnome-online-accounts] Don't assume that secret_password_clear_sync() returns FALSE on error

    Don't assume that secret_password_clear_sync() returns FALSE on error
    
    The secret_password_clear_sync() function returns whether items were
    deleted or not, and returning FALSE does not indicate an error
    condition.
    
    Detect the error condition correctly, preventing erroneus error
    prompts about not being able to delete stuff from the keyring.
