Cannot read property 'createValueMap' of undefined

Issue type:

[ ] question [X] bug report [ ] feature request [ ] documentation issue

Database system/driver:

[ ] cordova [X] mongodb [ ] mssql [ ] mysql / mariadb [ ] oracle [ ] postgres [ ] sqlite [ ] sqljs [ ] websql

TypeORM version:

[X] latest [ ] @next [ ] 0.x.x (or put your version here)

Steps to reproduce or a small repository showing the problem:

@Entity()
export class User {

    @PrimaryGeneratedColumn()
    id: ObjectID;

    @Column()
    name: string;
}

If using PrimaryGeneratedColumn instead of ObjectIdColumn, I get an error :

Error:  TypeError: Cannot read property 'createValueMap' of undefined
    at MongoQueryRunner.<anonymous> (C:\Users\atro\Work\typeorm-typescript-mongo-example\node_modules\typeorm\driver\mongodb\MongoQueryRunner.js:573:98)

    at process._tickCallback (internal/process/next_tick.js:109:7)

The data is stored normally in the database. I just use the generated example:

// insert new users for test
    await connection.manager.save(connection.manager.create(User, {
        name: "Timber",
        email: "Saw",
        password: "test"
    }));

using @ObjectIdColumn instead of PrimaryGeneratedColumn works for me.

`ts import { Entity, PrimaryGeneratedColumn, Column, ObjectID, ObjectIdColumn } from “typeorm”

@Entity() export class User {

@ObjectIdColumn()
id: ObjectID

@Column()
firstName: string

@Column()
lastName: string

@Column()
age: number

}`

Thanks for taking the time to look into this! You missed the point where I changed the id to match the RDBMS database type ( or this is my thought at least ). If you change the User id which resides in src\entity\User.ts to use PrimaryGeneratedColumn decorator instead, we get this problem
