Closed Issue: CF Stored Procs :: error when creating migrations that map to stored procedures with inheritance and Many-Many relationship [1252]

Probably related to (i.e. caused by) https://entityframework.codeplex.com/workitem/1251, but filing just in case because experience is slightly different.

Create the following model:

```
public class Order
{
public int Id { get; set; }

public ICollection<Product> Products { get; set; }
}

public class InternationalOrder : Order
{
public string Country { get; set; }
}

public class Product
{
public int ProductId { get; set; }

public ICollection<Order> Orders { get; set; }
}

public class InheritanceContext : DbContext
{
public DbSet<Order> Orders { get; set; }
public DbSet<Product> Products { get; set; }

protected override void OnModelCreating(DbModelBuilder modelBuilder)
{
modelBuilder.Entity<Order>().MapToStoredProcedures();
modelBuilder.Entity<Order>().HasMany(o => o.Products).WithMany().MapToStoredProcedures();
}
}

```

Enable-Migrations
Add-Migration Mig1

This throws the following exception:

__Index was out of range. Must be non-negative and less than the size of the collection.
