If you don't want to call base.OnModelCreating and want to do your own mapping, your mapping should look like this:

protected override void OnModelCreating(DbModelBuilder modelBuilder)
{
    modelBuilder.Entity().HasKey(r => r.Id).Property(p => p.Name).IsRequired();
    modelBuilder.Entity().HasKey(r => new { r.RoleId, r.UserId });
    modelBuilder.Entity().HasKey(u => new {u.UserId, u.LoginProvider, u.ProviderKey});
}

If you put the key for IdentityUserLogin only on UserId, you get DbEntityValidationExceptions when using the default google login.
