Closed Issue: Migrations: mapping Many-Many relationship into Stored Proc, and then renaming one entity results in error during Update-Database [1234]

Repro
Create the following model:

```
public class Person
{
public int Id { get; set; }
public ICollection<House> HousesOwned { get; set; }
}

public class House
{
public string Id { get; set; }
public ICollection<Person> Tenants { get; set; }
}

public class MyContext : DbContext
{
public DbSet<Person> People { get; set; }
public DbSet<House> Houses { get; set; }

protected override void OnModelCreating(DbModelBuilder modelBuilder)
{
modelBuilder.Entity<Person>().HasMany(p => p.HousesOwned).WithMany().MapToStoredProcedures();
}
}
```

Enable-Migrations
Add-Migration Mig1
Update-Database

Then rename of class House to Apartment.

Add-Migration Mig2
Update-Database

following exception is thrown:

__Either the parameter @objname is ambiguous or the claimed @objtype (COLUMN) is wrong.__
