Foreign keys removed from owned tables when excludedFromMigrations set to true

First issue
If you are working on a project that deals with a owned relationship but you are not the service that is in charge of the tables you will set excludefrommigrations as true. However this does not work as intended, it will remove all of the foreign keys related to that relationship and then not readd them again.

• If this is done a single time the downside will be no foreign key constraints
• if a second migration is added it will attempt to remove a key that does not exist and result in an exception.

    public partial class Dependent2 : Migration
    {
        protected override void Up(MigrationBuilder migrationBuilder)
        {
            migrationBuilder.DropForeignKey(
                name: "FK_Children_Parent_ParentId",
                schema: "Dependent",
                table: "Children");
        }

        protected override void Down(MigrationBuilder migrationBuilder)
        {
            migrationBuilder.DropForeignKey(
                name: "FK_Children_Parent_ParentId",
                schema: "Dependent",
                table: "Children");
        }
    }

Second issue
When creating migrations on owned relationships the tooling will add a line trying to call a method that doesn't exist to each entity, currently this will need updating manually in both the migration file and the snapshot file

Attached Repository should demonstrate both of these issues
