migrationBuilder.InsertData is not nullable compliant

[osjimenez]

When I define seed data with HasData method the generated code for migration uses this syntax:

migrationBuilder.InsertData(
                schema: "dbo",
                table: "Table",
                columns: new[] { "Column1", "Column2" },
                values: new object[] { false, null });

If I defined enable in csproj, this code don't compile.
The problem is for values parameter, must be object?[] type instead of object[] type.
