HasKey() on an overridden property ignores Column name attribute

[taisbak]

When specifying HasKey() for an overridden property the column name attribute is ignored.

Steps to reproduce

In the following code sample, toggle the HasKey() in DbContext.
When it's commented out - it works as expected.
When present - you get an exception: "Invalid column name 'ObjectId'."

It works in EF 3.1.

using System.ComponentModel.DataAnnotations;
using System.ComponentModel.DataAnnotations.Schema;
using System.Linq;

using Microsoft.EntityFrameworkCore;

public class SysObjects
{
    public virtual int ObjectId { get; set; }
}

[Table("tables", Schema = "sys")]
public class SysTables : SysObjects
{
    [Key]
    [Column("Object_id")]
    override public int ObjectId { get; set; }
    public string Name { get; set; }
    public int Schema_id { get; set; }
}

public class MyContext : DbContext
{
    public DbSet<SysTables> Tables { get; set; }

    protected override void OnConfiguring(DbContextOptionsBuilder optionsBuilder)
    {
        var _connectionString = @"Server=(localdb)\mssqllocaldb;Database=Master;";
        optionsBuilder
            .UseSqlServer(_connectionString);
    }

    protected override void OnModelCreating(ModelBuilder modelBuilder)
    {
        modelBuilder
            .Entity<SysTables>()
            .HasKey(e => new { e.ObjectId }) // comment out this line to bypass the bug
            ;
    }
}

class Program
{
    static void Main()
    {
        using var _dbContext = new MyContext();

        var Query =
            from t in _dbContext.Tables
            select new { t.ObjectId, t.Name };

        var TableInfo = Query.FirstOrDefault();
    }
}

### Further technical details

@AndriySvyryd I am able to reproduce this on a 5.0 daily. In 3.1, the table mapped is:

CREATE TABLE [dbo].[tables] (
          [Object_id] int NOT NULL IDENTITY,
          [Name] nvarchar(max) NULL,
          [Schema_id] int NOT NULL,
          CONSTRAINT [PK_tables] PRIMARY KEY ([Object_id])
      );

But in 5.0 it is:

CREATE TABLE [dbo].[tables] (
          [ObjectId] int NOT NULL IDENTITY,
          [Name] nvarchar(max) NULL,
          [Schema_id] int NOT NULL,
          CONSTRAINT [PK_tables] PRIMARY KEY ([ObjectId])
      );

Now it works for me too :-)
Thank you for swift resolution.
