fix(types): init method should use all attributes

[zaggino]

When you try to compile the example from https://github.com/sequelize/sequelize/blob/master/docs/manual/other-topics/typescript.md

You get an error:

error TS2345: Argument of type '{ id: { type: DataTypes.IntegerDataTypeConstructor; autoIncrement: boolean; primaryKey: boolean; }; name: { type: DataTypes.StringDataType; allowNull: false; }; preferredName: { ...; }; }' is not assignable to parameter of type 'ModelAttributes<User, UserCreationAttributes>'.

This fixes that error.

cc @hsource from #12405

Ah, my bad! I think I'd accidentally changed it when I was testing it.

Looks great!

Error: /home/travis/build/sequelize/sequelize/types/test/models/User.ts:50:3

ERROR: 50:3  expect  TypeScript@4.0 compile error: 

Argument of type '{ firstName: DataTypes.StringDataTypeConstructor; lastName: DataTypes.StringDataTypeConstructor; username: DataTypes.StringDataTypeConstructor; groupId: DataTypes.NumberDataTypeConstructor; }' is not assignable to parameter of type 'ModelAttributes<User, UserAttributes>'.

  Property 'id' is missing in type '{ firstName: DataTypes.StringDataTypeConstructor; lastName: DataTypes.StringDataTypeConstructor; username: DataTypes.StringDataTypeConstructor; groupId: DataTypes.NumberDataTypeConstructor; }' but required in type 'ModelAttributes<User, UserAttributes>'.

@zaggino You should be able to run linting locally

I'm going to go ahead and also just make the Typescript example better and tested. I'll do that in a separate pull request

Thanks again for the fix and sorry for the earlier error in the types! I've incorporated it into a larger fix and update of the documentation in #12435
